The Dresden Files: Twin Cities
The River of Lost Souls
The River of Lost Souls is a stream of living echoes that traverses every part of the Nevernever. Lorists argue if the collection of ghosts or actual souls, and if it actually traverses any plane, or if it is a natural channel for the collective emotions of those who are lost.
Regardless, the River represents a tremendous spiritual reservoir of power. Many gods and beings of power have attempted to draw upon the power of the River, only to be devoured by it.
This point corresponds to the parking lot of St. Christopher's Episcopal Church in Roseville.
