Hub 1: Seven Portals
Seven Portals is the first hub of Hexen. It is generally regarded as an introduction to the rest of the game. In the context of the story it is referred to as a test - the levels are "guardians", meant to defend the world of Cronos from invasion. The guardian realms have distinct elemental themes: Fire is one of the classical elements, Metal is a classical Chinese element, and Ice loosely corresponds with Water.
Upon completing the Winnowing Hall and entering the hub proper, Korax issues his iconic taunt: "Greetings mortal, are you ready to die?"
There is no intermission text introducing this hub in the PC version.
