The Tower of Chiros is the largest construct not only in Yipper, nor just in Mercury, but in the entire Universe, as it is 32,191.6 feet tall, taller than Mount Everest. The tower was built by Chiros, ancestor of Galaxeegee, to test the might of mercurians everywhere. It is made from Peryite, meaning that it is immune to everything except for the Great Forge that made the tower in the first place. There are 500 floors, each containing a challenge, with a great beast waiting at the top of the tower. The prize for the one who is worthy of the title of Mercurial King. No-one has beaten the tower yet.
