Ancient Dungeon

The Ancient Dungeon is a ruin from the age of gods lying beneath Alveria's capital. It was here that the legendary founding hero Warlock imprisoned the demon-god of vengeance Morrigan with a temporal seal built on scripture magic, leaving behind an unlock code.

The dungeon teems with demons, and time within flows roughly more than ten times slower than outside: a single day in its depths equals more than ten days on the surface. In the finale the demon-turned Reina destroys the castle's supporting pillar, opening the entrance, and 'abducts her own self' into these ruins - the very place Varis descends after her to destroy Morrigan and save Reina.
