The Tower of the Catacombs

"Woe betide those that enter here. - Inscription before the entrance of the Catacombs"The magical prison for Wefveriin the Traitor-King and his followers, the Tower of the Catacombs is on the island of Naur, off the eastern coast of Delin. The tower is actually inverted into the depths of the earth, where it is said to open to the waters of the abyss at the final level. The location of the tower is not well-known, as magic that surrounds the island tampers and disorientates minds.

History
The Tower was planned out by the King and the Dragon-Lord Ágnaron as a method to keep all high security prisoners enclosed in a prison that would "break their mettle".

Powers
The Tower is protected by powerful repulsion magic that prevents those trapped inside from coming out. It also unconsciously evokes an aura of dread that is supposed to repel all life from it from entering.
