Description
It's a map of Rashemen, a land in the continent of Faerun in the Forgotten Realms universum (the same Baldur's gate, Icewind Dale and Neverwinter Nights are set in). Rashemen lies in north-eastern Faerun. This barbaric land is inhabited by Rashemi, long-time enemies of Red Wizards from Thay.
The map is based on maps taken from FR wiki. It's a compilation of them.
WARNING: this map contains some non-canon locations, which I created to use in my custom D&D campaign.
