Page "Hexen II" Paragraph 2

Thyrion is a world that was enslaved by the Serpent Riders.

The two previous games in the series documented the liberation of two other worlds, along with the death of their Serpent Rider overlords.

Now, the oldest and most powerful of the three Serpent Rider brothers, Eidolon, must be defeated to free Thyrion.

Eidolon is supported by his four generals, themselves a reference to the Four Horsemen of the Apocalypse.

To confront each general, the player has to travel to four different continents, each possessing a distinct theme ( Medieval European for Blackmarsh, Mesoamerican for Mazaera, Ancient Egyptian for Thysis, and Greco-Roman for Septimus ).

Then, finally, the player returns to Blackmarsh in order to confront Eidolon himself.
