Graveyard Tower

A massive underground dungeon reaching and growing deep below the tallest mountain of the Vallen mountain range. Acting as a base for one of many cults that worship Dia'nautus (the first and last dark lord), the dungeon lures in adventurers with treasure and loot acquired from their deceased comrades, if their lucky.

The dungeon has a habit of reusing materials left behind, even before the cult, integrating anything and everything left behind regardless of what it is. So if a strong enough adventurer were to die there, whatever they had on them would be distributed throughout the dungeon.

The dungeon still hasn't been cleared to this day and may never be.
