Situated on the northeast finger of the Péninsule Diluvienne the Marais Rouges is a marshy landscape home to the Raveneye clan of Drow.

Recently a tribe of deep water Sahuagin from the Mer du Tonnerre has intruded into the Marais Rouges disrupting trade between the Raveneye Clan and Maison Kundarak enclave in Cap-Tempête. Maison Kundarak has been actively recruiting adventures and warriors to wade into the Marais Rouges and help restore the Raveneye Clan.
