While you were battling the evil forces of D'Sparil, the other Serpent Riders were busy sowing the seeds of destruction in other dimensions. One such dimension is the decaying world where Hexen takes place. A world littered with the mangled corpses of nonbelievers and inhabited by the undead followers that executed them. Only three humans &endash; a warrior, a mage and a cleric &endash; have escaped the leaders' vicious spell. Now these brave souls have sworn to crush the evil regime that threatens to destroy the world forever. Separated upon entering the mystical portal, the three are forced to attempt on their own what they had hoped to do together: find Korax's stronghold, destroy him and restore order in the physical world.
A sort of semi-sequel to Necrosis. You can read the description for the premise of the story.
Still phased after your trek through Korax's homeworld and beyond, rebuilding Cronos has been far from a flawless experience. Much of Korax's minions still wander the world, most unfound by any tasked to slay them.
That is, until one day you get a summons to the town of Riverwood, academic stronghold where all three orders mingle under the root of nature. Korax's minions have regrouped, but under who none can assess.
You arrive at Riverwood to find the town already overrun. This mission is no longer a defense on your part... it's an assault. You swear to the gods that you WILL get to the bottom of this. Readying your strength, you walk through the town gates, which swiftly close behind you....
