The Crossroads
Existing between the land of Tethys and the lands of the gods, the crossroads serves as a network, a place of transition. What little you know of it has been passed on by Mother Brolma of the Order of the Turned Leaf. She spoke of time that she traveled it in her younger years, when searching the planes for a cure to her hexed blood and the troubles it's caused. She was ultimately unsuccessful, but did provide the group with a metal cube she called, "The Anchor". She said it was a necessary component to traveling the planes successfully unless they happened to find someone who had already been there, as planar travel is extremely dangerous unless summoned.
