The Returners are a group of around 200 people native to Eberron who have ended up in Ambria (through The Mournland) and are trying to find a way back home.
The group is unknown to native Ambrians. Most Returners have settled into a comfortable life in Ambria, and there are some who may not even want to go home.
They are mainly spread between Yndaros and Thistle Hold, with the bulk in the latter, using it as a base for exploring Davokar, trying to find some sort of magical means to get home.
