Caller in the Darkness

The Caller in the Darkness is an entity made up of consumed souls that resembles a enormous whirlwind. It's current know location is the Gray.

Xa'oc encountered the Caller in the Darkness in the Gray after being compelled there by the sword Mist Song. The Caller attempted to consume Mist Song and Xa'oc, but he was saved at the last moment by the spirit of his former gladiatorial master, Navarro. During the process, Navarro's soul left the Caller and entered Mist Song.

Navarro's spirit is currently the only known soul to have escaped entrapment within the Caller in the Darkness.
