A mystic ruin that is well guarded by the family of Dro’Hizzir a great upper class of Shadow Warriors. This is unknown to everyone except for Dro’Hizzir. Knowledge that is only passed down from his forefathers and ancestors alike. Well underground in the city of Pulca. The entrance is found in Dro’Hizzir’s office in his ancestorial vault (that has riches in it as well). In the back of his vault is a narrow tunnel way big enough to fit a normal man in that leads to a ruin of his dead Ancestors and riches of the deceased.
