Grand Citadel

The Grand Citadel is an ancient Aeternii structure built in the Ancient Era at the center of Aeternum.

It contains a massive underground dungeon complex filled with twisting corridors, complex puzzles, deadly traps, and many powerful, armored undead warriors. Many have perished trying to find its end - if there even is one - and none have succeeded. To make matters worse, the dungeons seem to shift and change periodically, making progress through them extremely difficult.

Its original purpose is unknown.
