Evil Draws Near

Now you must use the Dread Relic in a foul necromantic ritual if you wish to challenge Teribus the Cursed. To the northeast, beyond Auchindoun, is the Writhing Mound, a place where necromancers gather.

The auchenai death-speakers and doomsayers carry doom skulls that are laced with powerful necro-enchantments. If you collect enough skulls you can use their power along with the power of the Dread Relic to command Teribus to face you.
