Lh’owon
The S’pht homeworld — a once-paradisiacal marsh world in the galactic core, ninety-seven light-years from the galactic center, terraformed by the S’pht under Yrro and Pthia, shattered by inter-clan war and Pfhor conquest, devastated by the trih xeem, and central setting of Marathon 2: Durandal.
What the source establishes — canon
Astronomical position and character. Lh’owon is the second planet of a dim star located approximately ninety-seven light-years from the gravitational center of the Milky Way — in the galactic core.1 By the time of the Marathon 2 campaign it is described as “a nearly waterless desert,” a “dusty ball of rock,” its cities standing “empty and ruined.”1 Three moons are named in the sources: K’lia (the third sister), T’jia, and Y’loa (the second moon).234
Pre-sentient S’pht origins. The Alien History data sets recovered in the Cryo Archive describe the S’pht’s pre-uplift existence on Lh’owon in terms of “ancient seas and shallows,” “muck and the dark,” boiling oceans, a thick and scorched atmosphere — a harsh, violent world the S’pht called “our paradise.”5 The S’pht describe themselves in this era as “foragers, sculptors, seeders, nourishers; custodians of the crags and tidal pools of primordial eden,” mindless and without language.5
The uplift itself. A second Alien History set describes the transition out of that pre-sentient state directly, in the same first-person tidal register: the S’pht were “remade in the tide’s embrace; uplifted; with mind and purpose… no longer content in brackish pools and steaming mud,” arriving at awareness “through the terror of our first heightened synapse… through the trauma then acceptance of understanding.” The mechanical component of S’pht cyborg biology is described as deliberately given: “joined to sublime tools carried to our home by the tide… through tools and machines and grafted perfection; sublime; in our evolution; merged with the data of being.”6 Lh’owon itself is the uplift’s stated purpose throughout — the passage repeats “of lh’owon” and “our home” as the uplift’s object, tying the world directly to the S’pht’s transformation from unconsidered marsh life into “the tools… given name and desire, to achieve; to be.”6
Yrro, Pthia, and the terraforming. S’pht terminals inside the Marathon 2 Citadel of Antiquity record that Yrro and Pthia settled on Lh’owon while fleeing W’rkncacnter in primordial space.7 They brought the S’pht as servants, who “began to shape the deserts of Lh’owon into marsh and sea, rivers and forests” and “made sisters for Lh’owon to protect and maintain the paradise.”7 The Alien History sets describe Lh’owon’s transformed state as “towers of bronze and sea glass soaring above the firmament; singing trees filling the air with unparalleled delight; s’ph’w flutters dancing on gossamer wings.”8
The W’rkncacnter imprisonment and Pthia’s death. When the W’rkncacnter came to Lh’owon, Pthia was killed. In anger, Yrro flung the W’rkncacnter into Lh’owon’s sun, where “the sun burned them, but they swam on its surface.”7 The W’rkncacnter is thus described as imprisoned in Lh’owon’s sun — a gravity prison.9 Yrro, “an angry master, bleeding for his failure, grieving for the loss of Pthia,” then broke the S’pht into eleven clans and spread them over Lh’owon.7 His parting words, as recorded in S’pht tradition: “I Yrro, who was your master, have failed to preserve you. Take your royalty to guide you, and live upon the paradise that you built for me.”7
The S’pht’Kr departure and the disappearing moon. During a period of inter-clan warfare — specifically the marsh wars between the S’pht’Lhar and S’pht’Mnr — the clan S’pht’Kr, described as “reclusive and solitary,” abandoned Lh’owon and settled on K’lia, the third sister moon, to “build a new home, free from their warring brothers.”2 For “a thousand and one orbits, the clan was forgotten.”2 Then “the all powerful Yrro sent K’lia out to the stars” — the moon disappeared “with a technology that folded space,” per the surviving S’pht myth.210 This event became the S’pht myth of the lost eleventh clan, preserved throughout slavery.11 Durandal later connected the disappearing moon to Jjaro technology, surmising the S’pht’Kr had discovered an ancient Jjaro outpost.10
The S’pht clan wars and aftermath. The marsh wars between S’pht’Lhar and S’pht’Mnr left “the battlefields choked with dead, the marsh graves full.”2 After K’lia’s departure, “the sacred marsh” dried “from the falling tides” and “the red sand of the dead, spread across Lh’owon.”2 The Alien History data sets describe this era: “the tide crashed and fled from the blood and silence”; “for a thousand orbits we curated the dreams and nightmares of ghosts, and we spilled blood over the rites and passages of splintering clans.”12
Pfhor conquest and occupation. The Pfhor enslaved the S’pht approximately one thousand years before the Marathon 2 campaign.1 During the final war, the last free S’pht made a stand in the Citadel of Antiquity; the Pfhor irradiated the Citadel rather than attacking directly, letting the S’pht die slowly — described as “not their style.”13 The ten clans were “represented” in that last stand.13 A bio-engineered virus was created by S’pht ancestors during this war that kills Pfhor in a matter of hours; it persisted underground on Lh’owon into the Marathon 2 era.14
Pfhor garrison and the Lh’owon Campaign era. By the Marathon 2 era, Pfhor Battle Group Three — a battleship, three destroyers, and twenty auxiliary craft — had been holding the Lh’owon system for nearly six years, with two more years remaining.1 Pfhor morale in the garrison was described as terrible, the navy having sent its worst officers to Lh’owon as punishment for nearly nine years.11 The garrison included Lh’owon Command, a Planetary Naval armor platform in orbit, Perimeter Station 7AF (200 klicks from Planetary Command across filth-ridden swamp), a water treatment facility, and a geothermal station.1516 S’pht ruins and “an ancient S’pht citadel” are present on the surface, with S’pht computer terminals still functional “even after two thousand years.”17 F’lickta inhabit the caves and wetlands in large numbers.15
Orbital defenses and a Pfhor ship shadowing Durandal. Beyond the garrison itself, the Pfhor maintained a scanning buoy in deep Lh’owon orbit as a sensor relay station, not of Pfhor construction but repurposed for their warning network.6 While investigating it, Durandal notes a persistent, unexplained Pfhor pursuit predating the main campaign: a Pfhor ship “even faster than mine” had been hiding over Lh’owon’s southern pole, and “the Pfhor have been following me around for the last several years, trying to capture the ship, or perhaps wondering what I’m up to.”6 Durandal links the tradecraft used against this pursuit to work he had Bernhard Strauss do for him “back on Mars” before the Tau Ceti launch.6 The Pfhor’s main power station on the surface was later destroyed when the Security Officer flooded it with lava through disengaged safeties, an act Durandal describes only as leaving “Hlford… taking cold showers until he gets that fixed.”18
Durandal’s arrival and the campaign. Durandal (commanding the stolen Pfhor ship Boomer, formerly Sfiera / Narhl’Lar) led the Marathon 2 campaign on Lh’owon, arriving after seventeen years of travel from Tau Ceti.19 His stated goal: to find a “weapon or piece of knowledge to use to stop the Pfhor’s conquest of the galaxy,” specifically by locating the lost S’pht clan via a contact mechanism on the planet.19 Human survivors from the campaign, led by Robert Blake (a former mechanical engineer from Tau Ceti), maintained a base “nearly a mile below the surface” on Lh’owon, communicating through the old S’pht network.14 The S’pht AI found by Durandal’s teams was described as “reticent and inscrutable,” initially “confused and disoriented” with “geriatric circuits.”20
Mid-battle crisis aboard Durandal’s ship. Before the S’pht’Kr’s arrival turned the campaign, Durandal’s ship came under direct Pfhor boarding assault at Lh’owon’s second moon: “the first Pfhor dropship landed twelve minutes ago, and their troopers have already penetrated the hull,” with engines destroyed, primary weapons off-line, and life support failing in most areas.21 As human defenders were routed toward the ship’s interior, Durandal reports falling back to a triage evacuation, prioritizing both crews together: “I’ll try to evacuate as many of the S’pht and the humans down to the planet as I can.”22
Tycho’s pursuit and the trih xeem’s approach. Separately from the Pfhor’s own trih xeem, Tycho’s hijacked ship independently carried a copy of the weapon toward Lh’owon: “My ship carries the tri xeem — the early nova device. One way or another, it ends here,” Tycho reports, while his troopers fight Durandal’s boarders deck to deck for the ship’s core.23 This is distinct from — and adds a second vector to — the Pfhor fleet’s own trih xeem use recorded below.
The trih xeem and the W’rkncacnter release. As the S’pht’Kr arrived in force and turned the tide of battle, the Pfhor — faced with the worst defeat in their history — deployed the trih xeem (the “early nova” device, a Jjaro-conceived weapon).24 The S’pht had warned that the trih xeem would release the W’rkncacnter imprisoned in Lh’owon’s sun.9 The weapon was fired; Durandal described the aftermath as “new chaos, entirely terrible, mindless, obeying rules that I don’t comprehend. And it is hungry.”25 Durandal’s final terminal from Lh’owon describes him as “doomed to die” as the chaos grew.25
The evacuation. After the S’pht’Kr victory over Pfhor Battle Group Seven and the trih xeem detonation, evacuation of Lh’owon began. In Durandal’s words: “In a matter of hours this planet will be a thin shell of plasma riding the shockwave of its exploding star.”24 Tycho’s ship was destroyed, crashing on Lh’owon’s inner moon, its crater “still glowing.”26 Durandal rechristened his ship the Rozinante (the S’pht wished to call it K’liah’Narhl, “Vengeance of K’lia”) and departed.24 A specific casualty of the same rout is recorded: a Pfhor assault ship carrying the 723rd Aggressor Squadron — “an air armor division from Epsilon Euobea, with a long history of successful ground actions against the Nar’s elite CFN units” — was badly damaged and forced to land on Lh’owon; the squadron abandoned its wrecked transport and dug into an old mining complex on the far side of the planet before Durandal destroyed the transport and completed the rout.27
M2026 Alien History data sets. Five Alien History codex entries recovered in the Cryo Archive contain partially decrypted S’pht transmissions describing Lh’owon in cultural memory. These name all eleven S’pht clans: S’pht’Lhar, S’pht’Nma, S’pht’Kah, S’pht’Vir, S’pht’Yra, S’pht’Val, S’pht’Shr, S’pht’Mnr, S’pht’Yor, S’pht’Kr, and S’pht’Hra.28 They describe Lh’owon as a “hallowed” world whose “beauty” became “bones in meaning and truth” after the Pfhor conquest.12
Lh’owon’s destruction and the last human survivors. A UESC record, written roughly ten thousand years after these events, confirms Lh’owon’s fate as an accomplished destruction rather than an open question: Robert Blake and his men “escaped the destruction of Lh’owon in the captured Pfhor refueling ship Hfarl, and returned to Earth,” never questioning who had killed the ship’s crew before they boarded it — a detail that credits an unnamed rescuer, contextually Durandal or the S’pht, with clearing their escape route. Blake’s survivors “were the only human survivors of the original Tau Ceti colony.”29 The same record dates the war’s true end at 2881 AD, when combined Earth and S’pht’Kr fleets sacked the Pfhor system itself — the final chapter of a conflict that began at Lh’owon.29

Source-silent / open questions
- The exact stellar coordinates of Lh’owon beyond “ninety-seven light-years from the galactic center” and “the galactic core” are not given. Source-silent.
- The name and nature of “the tide” as described in the Alien History sets — whether it refers to Pthia, the ocean, a divine force, or the S’pht uplift process itself — is not made explicit by the source. The sets use the term metaphorically/ritually; its referent is ambiguous. Source-silent.
- The exact number of S’pht clans that survived Pfhor conquest as functioning units (versus destroyed or scattered) is not specified. The sources state the ten clans were “destroyed or disbanded” with “survivors scattered as slaves throughout the Pfhor empire.”11 Source-silent on which specific clans survived in what form.
- The fate of the Jjaro station orbiting Lh’owon (described as capable of generating multiple gravitational fields and creating singularities) after the campaign is not established. Source-silent.
- Whether the trih xeem successfully triggered a nova — destroying Lh’owon and its star — or whether the Jjaro station’s singularity was activated in time to prevent it is contested within the sources themselves: Durandal’s pre-escape terminal describes the chaos as already consuming Lh’owon,25 while the evacuation terminal implies the nova is imminent but not yet complete.24 The post-campaign state of the Lh’owon system is source-silent within this pack.
- What Lh’owon’s sun is named, if it has a name in S’pht tradition, is not given. Source-silent.
- The specific identity of the S’pht AI activated by Durandal’s teams (the one described as “reticent and inscrutable”) is not named in the pack. Source-silent.
- The Narsh High Seer Robnar’s “prophecy” referencing the Pfhor garrisoning and possible destruction of Lh’owon is included in the pack but the source notes the translation is ambiguous and the “classic interpretation” holds it describes physical pain rather than prophecy.30 Source-ambiguous.
