Thysis is the third hub of Hexen II.
The hub takes place on the Egyptian-themed desert continent of Thysis, and features the hardest puzzles in the game. The main goal is to find and retrieve the two Crowns of Egypt. Another tasks is to collect all four Canopic Jars and return them to the Dark Pharaoh's tomb.
Time is a major motif throughout the hub. A clock has to be used to change the time of the day, as one of the necessary Artifacts is hidden behind a door that opens only at a certain hour. The hub also features time travel, which is necessary to solve several of the puzzles. Certain areas of some levels are only accessible in the past, while others - in the present.
When the two crowns have been recovered, the way to Pestilence's Lair will be open. Victory in this battle takes the player to the fourth hub.
