Erymanthus is the floating isle upon which the city of Arcadia resides. The only way onto the isle is through a magical archway on top of Mount Nicator in the Southern Vashnars. To enter, simply speak the name Arcadia.
Erymanthus harbours a diverse community of wildlife, including bears, ducks, and a rare species of bird. The Erymanthian woods surround most of the mountainous island, while Lake Stymphalus can be found on the eastern side, with Mount Erymanthus riding in the centre. The Atavian city of Arcadia is located on the southern face of Mount Erymanthus.
Not many people live on the actual isle, though you can find Heliastes, a blacksmith, and a small family on a farm in the area.
