Orsinium

Orsinium is a formable country, and can be formed by any nation with Orsimer as their primary culture. It can go on to form Wrothgar State. It is most commonly formed by playing as Orsimer State at any bookmark. Orsinium is rather powerful, especially with the Orcish Fury modifier, and dominates Central High Rock. Expansion can occur east to form Wrothgar, west against the Bretons and Direnii Elves, or South against the Corelanyan Clans. Later Conquest can move into the Half Bloods of Reach and Northeastern Hammerfell.

Additionally, if starting as Orsimer State their starting idea includes a colonist. Thus this nation is already well suited for colonizing northern High Rock and moving onwards to Yokuda and Coastal Tamriel. Because the orcs have a limited presence in High Rock aggressive expansion will be problematic until the player forms Orsinium which has a powerful National Tradition of  -25  Aggressive Expansion Modifier.
