Skull of Mondain

The Skull of Mondain is a very evil artifact. If used in an area with other living beings, these beings are all destroyed by the sheer power of the evil within this skull. However, as it is with such evil, the price is high and all virtues will flee the user of this dark skull.

When Mondain died, other dark mages were greedy to get his remains, as the dark power within them was great. Minax was horrified and in the last second saved the most powerful part from being defiled: her lover's and mentor's skull, enshrining it in her fortress. When her fortress crashed back to Sosaria, the skull was thought lost. In Ultima IV, the Stranger found it near three volcanoes, where later Terfin would be, at double new moon. Throwing it into the fiery entrance of the Abyss, this dark Artifact was destroyed forever.

Trivia

 * Funny enough, there is a serious blunder in Ultima IX, where the Skull is seen in the Museum. It is clearly wrong since Erethian, an expert on ancient artifacts, clearly states that the Skull is destroyed.
