Ustelus

Ustelus, the River of Souls, is a great flow of souls where the dead travel to and through to reach their final destination in one of the six Realms of the Dead. After entering the river and flowing down its rapids, the soul encounters The Great Fork, a place where souls are guided towards their final destination. Their journey ends when the travel to the end of that branch of the river, and are spit out at one of its six great mounts into one of the aforementioned realms.
