Galen dreams of being in a place more magical even than Sinai, where a wizard's tower – the Tower of Celesti – stands within a city of wizards, waiting to be explored. Joined by a woodsman cat by the name of Wren, Galen heads to the tower, first encountering what seems to be an enchanted doorknocker, with some ambiguous instructions engraved on the ring. They manage to open the door without incident, by rapping the knocker as instructed, whereupon they discover a table inside and a talking tea set. As they examine the room, it seems that there is a puzzle involved in reaching the top level, requiring that four gems – associated with the four elements – be placed in settings in the table. They are also distracted by a talking teapot, and a mischievous sugar pot.
