Forbidding

The Forbidding was the barrier beyond which Demons had been banished.

Before the birth of the New World, there had been a great war between good and evil which the Elves finally won by creating the Ellcrys and a Forbidding that banished the Demons into a timeless dark.

All who had followed or sworn to the Void were imprisoned there.

The magic of the Ellcrys held the Forbidding in place, preventing the from Demons escaping.
