I have studied the Dome's (First Level) geography roughly, making a map, and it is possible that the Irifon river flows from Bronze Doors to Ojaveda, and ends at some waterfall at the cliff leading to the Barn (Second Level), if my assumptions are correct. According to my map (I'm not a settings dev) Amdeneir would be close to the level's edge, so would Ojaveda.
