Description (Planetology)

The primary of the Iiu system is a tiny red main sequence star barely luminous enough to light or heat the world.

• Although Iiu’s atmosphere is rated as Exotic it resembles Terra’s: the main constituents are nitrogen and oxygen but it retains high levels of carbon dioxide, creating an extreme greenhouse effect.
• This raises the temperatures on the surface to levels that Humans can endure and S'mrii find comfortable.
• The presence of gases such as carbon monoxide and sulphur compounds serve to make the air un-breathable without artificial aid.

History & Background (Dossier)

Iiu was settled by S'mrii using sublight ships long before the First Imperium and even today the bulk of the population are S’mrii.

• The small colony survived the Long Night and was even able to maintain some contact with other worlds.
• The remains of the original S’mrii cities make Iiu a popular spot for those who enjoy amateur archaeology, although all digs are closely monitored by the rather repressive government.
