Bervirius, son of King Danthalas, was killed in battle. His devout mother Rashiliyia was so heartbroken that she swore fealty to Zamorak if he would return her son to her. Bervirius returned as an undead creature and terrorized the King and Queen. Many guards died fighting the undead Bervirius. Eventually the undead Bervirius was set on fire and soon only the bones remained. His remains were taken far to the South, and then towards the setting sun to a tomb that is surrounded by and level with the sea. This is the only way to contain the spirits of witches and the undead.
