Old Ruins

Centuries ago the ruins were a temple, used to worship the gods as well as store the history and knowledge, but it was abandoned because of the war and later, still during the fight of the gods, mostly buried. Without any visitors the nature rapidly claimed the area around the temple and today the building is located deep in the Black Forest.
But even after all the time has passed, the interior is mostly intact. A few chasms, destroyed ceilings and collapsed walls can be found, but besides that someone could still use it, if it wasn't for it's past...
