Praxys is a great tower of stone, which breaks upward through a headland of limestone. It is massive in size, beyond any human scale, towering more than 1,500 feet into the air. It was carved from a small mountain that arose out of the ocean. The tower is 200 feet across, and its interior is filled with vast empty spaces that serve as storage chambers and prisons. Only three floors are designed to be habitable by mortal creatures, and each of these floors have ceilings that are 30 ft. in height, in order to accommodate Titans and giants.

Across many miles of ocean, Sydon’s tower projects a piercing ray of silver light, which searches for trespassers. This light radiates from the heart of a star that Sydon has imprisoned at the pinnacle of the tower.

A huge stone dock juts out to the south. It was built for ships manned by gygans or cyclopes, not for human vessels. The dock is protected by a dozen ballista crewed by

• Gygans (appendix B). Each gygan can load, aim and fire its ballista in a single round due to their size and six arms.
