A Crypt is one of many generated structures found in Vethea. It can be found on layer 1. Crypts are small structures with entrances aboveground surrounded by metal caging. Crypts contain Crypt Keepers, which can give players Amthirmis Lumps.
From the entrance, one can go into the crypt. The crypt itself doesn't have much except for a few small rooms. Be careful when going into the crypt, however, as it contains a Vermenous spawner.
