The Etallen's Crypt is under the most important temple of Zetania. Inside It has got its national symbol, "Cepeus", which even appears on its national shield. It is a simple room with an groin vault and some reinforcements at its corners. Cepeús is inside a cylindrical showcase. This place can rarely be visited by visitors, with exception of important occasions. I made this concept from the views of two opposite corners, from inside and from outside (although it is buried). After I mixed it with a transparency effect to see the inside from the outside.
