Ilium is a moderate population world, too many sophonts to be an agricultural world but not enough to be an industrial world. It is a member of Darrian Confederation in the Darrian Subsector of Spinward Marches Sector. This world supports a Military Base and the system supports a Naval Base. 100% of the world's population is the Minor Human Race Daryen.

Astrography & Planetology

Ilium is a member of the Spinward Main.

Ilium, except for its sulphuric taint, seems like a perfect Darrian planet with its warm, thin atmosphere and productive agriculture. This is because the pre-Maghiz Darrians terraformed its atmosphere by seeding bacteria and plants for decades before human colonists settled permanently. The sulphur was a by-product of their efforts to make the planetary crust out-gas more efficiently.

Native Lifeforms

The rat-like marsupials known as Thihk are widely despised. Every couple of decades an explosive breeding pattern results in dangerous swarms of these small carnivores.

History & Background (Dossier)

The Te-Zlodh name for this world is Yelim, which means "pioneer."

Ilium is a Darrian Confederation world located in the Darrian Group in Darrian Subsector of the Spinward Marches. After the collapse of the original Darrian interstellar nation, Ilium survived the isolated centuries fairly well, but remained at a very low tech level. Its inhabitants had gradually developed to about TL-8 when they were recontacted from Mire (Spinward Marches 0527). Today Ilium is a major naval base.

World Starport (Sp)

Ilium has a Class B Starport, a good quality installation which includes all the expected amenities including refined fuel for starships, brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing annual maintenance, overhauls and most kinds of repair, and construction of non-starships. Most ports of this classification have both a Highport and a Downport.

Expanded Historical Data

"Yelim" is Te-Zlodh for "pioneer." The world was terraformed by pre-Maghiz Darrians to increase the world’s surface atmospheric pressure, and a slight, still extant sulfuric taint is evidence of those efforts. Iilium was settled for its extensive mineral resources, and to provide additional agricultural resources for the homeworld and the other colonies.

The world was isolated by the Maghiz, and was lucky enough that most of the terraformation process was complete when the EM wave from Tarnis arrived, so there was no loss of life due to the planets un-inhabitability. By the time the world was recontacted by Mire, it had developed extensive agricultural regions, and the world was instrumental in aiding the recovery of the Confederation through its export of cheap foodstuffs.

1105

Ilium is dominated by a small council of industrial landlords, mostly corporate executives that control most of the planets industry and agricultural land. The world's law level is pretty low, and the council doesn't govern much beyond guaranteeing its monopoly over the planets economic base. Below these lords, a complicated pyramid of local suzerains and chieftains handle administrative affairs, seeing to the needs of the common citizens with only some outside support.

The world is only a few decades away from becoming an industrial world in its own right. The local government has encouraged this growth through careful investment, and occasional invitations to outside companies to set up plant and join the governing council.

New Era

Since the Collapse a number of outside firms had this honor of invitation extended to them: Ling-Standard Products, General Products, Prynde Metals, Grand Design, Oberlindes Lines and Spinakker. Iilium has also become very heavily concentrated in the manufacture of TL 9-11 vehicles and transportation components, and heavy military products as well. The government hopes to intensify this activity by increasing the local technological base to construct the higher TL goods that are in more demand within the Confederation and the Regency.

A number of obstacles have arisen to upset these plans. Several ecological groups have objected to the scope of these plans, and they have a significant base of support among the locals who fear that the planet will become an industrial eyesore. On the opposite side, the industrial expansion has tested the councils control over the planet, as development and increasing prosperity has brought in groups of outsiders, from company execs to the new and growing middle class, which has challenged the council’s tightfisted control over life on the planet.
