Erebus

In Greek mythology, Erebus is the name of a place AND of a god, which may cause some confusion.

---

The god Erebus is the god of shadow and darkness.

The PLACE named Erebus is the no-man's-land between the shore of the river Styx and the Asphodel Meadows and is, like bathos said, the place that people go who've wasted their lives.

In Greek Mythology, the dead who had wasted their lives went to Erebus.
