Spinward of Gamelea Subsector lies Lymethius Subsector. Astrographically, Lymethius consists of the Tallu, Kalar-Wi and Yuakteisye Clusters and the Julnar and Aaron Reaches.
Ouron, Finduil and Por’via are Imperial worlds and are considered part of the Julnar Reach and, along with Anar, are part of the Duchy of Gamelea, while the Aaron Reach, named for the bright F5 primary of the Lysarnor System, contains the bulk of the population of the Geithurian Republic at Appaer, Geithur and Lysarnor.
The Tallu Cluster is divided between the Imperium, with its toehold at Anar; the Geithurian Republic, holding Jul’ni and Coroson; and the independent systems of Tallu, Auru and the dead world of Nearo. Only Kidan and Masaad of the Kalar-Wi Cluster lie within Lymethius Subsector. Kidan was seized by Huiha Esoyatre ihatei in 1106 following the collapse of the Kalar-Wi State at the end of the Kalar-Wi War. Now known as Yaitlaorail, the 40,000 Kalar-Wi of Kidan are seeing a massive influx of Esoyatre Aslan moving onto their planet. Yuakteisye Cluster consists of the four systems settled by the Aslan Huiha Esoyatre and lies across most of the trade routes between Lymethius and Cabria Subsectors.
A scattering of systems along the Spinward edge of Lymethius Subsector provide routes further Spinward into Per Vulia Subsector.
The 2nd Rimward War (793 – 794) in Gazul Subsector blunted Imperial consolidation of the Julnar Reach route around the end of the Perrsherrik Rift. The Geithurian Republic and Huiha Esoyatre formed an alliance to prevent further Imperial expansion through the Tallu Cluster and Huiha Esoyatre then became the driving force behind what is now known as the Outrim Alliance. The Outrim Alliance has fought four wars with the Imperium since the early 10th Century to contain Imperial expansion and fix the border fairly much where it is today.
Lymethius Subsector is home to two Major Races – humans of mixed Vilani and Zhodani stock, and Aslan – and three Minor Races: the ursoid Purvions of Tallu, while related to the Purvions of Lithia/Miazan, have a comparatively High Technology civilization and have successfully maintained their independence for nearly 1000 years; the diminutive psionic Aaronites from the warrens of Lysarnor are valued mechanics and crafts-sophonts; while the Tharoysa of Dysa Metharoth have a reputation as shrewd merchants.
There are a number of languages current in Lymethius Subsector: Cassingal: - dialect of Gazolin Imperial Basic, Cassingal has spread over the coreward border of Gamelea Subsector and is spoken on all the worlds of the Julnar Reach - Tulvan, Julnar, Leminkainen, and Ouron, Finduil and Por'via in the Lymethius Subsector. Gamelea Imperial Basic speakers and Cassingal speakers can understand each other, though quietly laugh at each other’s accents and spelling conventions. Gamelea Imperial Basic: - spoken on Anar, and by Gamelea Ducal officials on Ouron, Finduil and Por'via. Kassuriik: - main language of the Purvion Minor Race of Tallu and related to the Kassuriik spoken by the Purvions of Lithia/Miazan. Khasikha: - Vilani dialect used as a native language by the inhabitants of Appaer/Lymethius and subsequently adopted as the official language of the Geithurian Republic. Lhosuwha: - main language of the Tharoysa Minor Race of Dysa Metharoth/Lymethius. Phijudas: - main language of the Aaronite Minor Race of Lysarnor/Lymethius. Trokh Esoyatre: - dialect of Trokh spoken by Aslan of Huiha Esoyatre of Yuwe, Atlasiykh, Faiwawhwe, Yuakteisye and Yaitlaorail in Lymethius Subsector. Vriok: - main language of the Kalar-Wi Minor Race spoken on Kalar-Wi and the worlds of the old Kalar-Wi Empire, including Kidan and Masaad in Lymethius Subsector.
Lymethius Subsector contains twenty-six worlds with a total population of 186.202 billion sophonts. The highest population, A, is at Appaer and Yuakteisye, and the highest Tech Level, C, is at Appaer, Yuwe and Tallu.
