The Broken Crown
The dark recesses of tomb of the great Warlock Timbal were once disturbed by graverobbers. Pilfering treasures aplenty, they also made the mistake of knocking over a priceless vase – one that contained the bound spirit of Maltraxru.
The Devil watched the graverobbers for some time. They sold on most of their wares, including the Tome of Ensnaring – a powerful book that describes some of the bindings that keep Nerull bound to the Underdark.
Sensing the chance to free his Master, Maltraxru appeared before the purchaser of the book and offered him great power for the return of his assistance.
And thus, Salzar bound himself to the Reaper’s whims.
