Strahd and Azalin visit Mordent

In 579 BC, Azalin and Strahd collaborated in an attempt to break through the Misty Border surrounding Barovia and escape the Demiplane of Dread. This attempt resulted in the pair arriving in the outworld realm of Mordent. There, the Apparatus split Strahd's personality into good and evil manifestations: Alchemist and Creature respectively. The Alchemist and Creature's attempts to destroy each other caused the escape attempt to fail, and forced Mordent into joining the Demiplane of Ravenloft. The vacuum left by their departure allowed Godefroy to assume darklordship. Strahd and Azalin remember only fragments of this time.
