The Shayzien Crypts are an ancient dungeon located in the south-western part of the Graveyard of Heroes, in the Shayzien House. Players must bring a light source with them or risk getting swarmed over with tiny insects. The crypts are visited during Dragon Slayer II.
The crypts were constructed long before the founding of Great Kourend 1,510 years ago, and is the burial grounds for the kings and queens of Great Kourend, until a few hundred years ago when undead zombies, skeletons and skeleton mages began to overrun the crypts, making the lower levels of the crypts difficult to visit. Throughout the crypts, the symbol commonly associated with Xeric can be seen.
In the lowest level of the crypts, the tomb of Camorra Shayzien, the founder of the Shayzien House, can be found. In addition, a tomb can be found north of hers, which appears to have been opened with blood spilled around it, and has collapsed into the floor below. It should be noted that the bloody tomb has the symbol of Xeric engraved on it.
