The Lost Seas
Built of rare golden granite from the far southwest, the Golden Tower sits at one end of the great gladiatorial arena of Tyr, opposite the mighty rainbow ziggurat; it is connected to the king’s viewing-booth in the arena (where Kalak was slain by Rikus’ spear) by an enclosed passage or colonnade. It is surrounded by the walled King’s Gardens and protected by the newly-formed Golden Guards (as well as by many ancient traps and magicks).
Once, it is rumored, the Golden Tower was connected to the ziggurat by a deep, obsidian-lined tunnel. When Tithian became king, he ordered it filled with sand and the ziggurat sealed.
