Ascavia is part of the great river lands of Shaoge, with lush fertile lands and large dense forests. Lying at the lower end of the Talaeieo river, Ascavia is mostly hilly in the west and north and flat elsewhere. The same partitioning can be made for where there is mostly forest and where the land is developed and worked by farmers. Ascavia has only a small coastland and this is mostly formed by the estuary of the Talaeieo river.
