Midgewater

The Midgewater Marshes are a land east of Bree-land and the Chetwood. It is a large bog, with brown grass, stumpy trees, boggy pools, and possibly worst of all, midges. No Orcs spawn here. Instead there are clouds of annoying midges. The marshes are treacherous to cross.

Upon entering these marshes you gain the achievement "More midges than water."

Mobs
The only mobs that spawn here are the aforementioned midges. If you shoot down midges with a hired unit you get the achievement "Anti-air support." Due to midges, it is recommended to travel through the marshes with your sound off.

Vegetation
The only vegetation here is sugar cane, swamp oak trees (oaks with vines,) and brown grass.
