Mallus's realm

Mallus' realm is an extra-dimensional prison in which Mallus was kept alongside a variety of magical creatures. It was opened by the Legends so they could kill Mallus, allowing the rest of its inhabitants to escape.

History
At some point in the past, the ancient tribes of Zembesi came together to banish Mallus to this realm using the totems.

At some point in the past, some humans banished the Fairy Godmother to this realm for what seemed to her like an eternity.
