Skull of Mondain

The Skull of Mondain, the remnant of the once proud sorcerer, is an artifact of vast and evil powers. If its magic is invoked, all living beings in the vicinity of the skull's holder are slain, destroyed by the dark potency within the magician's bones.

History
It is likely that Mondain enchanted his skull to allow for such destruction well before his death, and scholars have speculated that he placed a magical matrix within his own head to achieve such an effect. Years after the wizard's demise, during the events of, the skull could be found deep within the sea, between three volcanoes to the west of the Isle of the Abyss. Only on the darkest of nights could the skull be retrieved, when both of the Brittanian moons were new.

There is only one man of whom it is known that invoked the powers of the skull: Jude. It is unclear what the circumstances of the skull's activation were, but Jude was long haunted by the weight of such a sin, and could for a time be found amongst the poor tended to by Julia of Minoc, debasing himself as he sought atonement for his crimes.

It is possible, that the Stranger, at Jude's behest, eventually found the skull and sought to destroy it within the fires of the Abyss during the hero's quest to attain the mantle of the Avatar. Erethian, an expert on ancient artifacts, later insinuated as much when the hero spoke with him on the re-arisen Isle of Fire.

However, centuries later, during the time of, the skull resurfaced as a curiosity within the Royal Museum of Britain. It is unknown if this appearance implies a failing on the part of the Avatar to dispose of the artifact, or if, through some perverse means unknown, the skull survived the Stygian flames into which it had been cast. While it could be that the item on display was merely a convincing replica, the mere suggestion of the skull's presence in later ages raises disturbing questions.
