Monstrously large caverns beneath the ground had become common place in daily life. Civilization revolved around these rapdily growing 'Dungons', slaying the creatures that endlessly appeared with sword and shield, claiming the loot as their own and sapping the rampant energy in the air to grow stronger.
Some tales spoke of a Dungeon so grand, legendary figures lined up just for the privilege of making it their final resting place, immortalizing themselves upon its entrance. It began as a simple mine, home to the place were an old beast rest. The very same who exiled her out of fear, became the fire that fuelled her ascension.
Those who scorned a woman sent to rest would see just how black their innards were.
