A sorceror, Cronyn learned of a prophecy from his mentor of a twice-blessed child that would be born on a special day when all magic would cease to exist in the world. He came to realize that Piper was carrying this twice-blessed child, and with the help of a female demon who called herseld Doris, he managed to isolate Piper while she was in labor, hoping to kidnap the child and raise it to be a powerful force for evil.

Spell to Vanquish Cronyn and Doris:
Use dust from a unicorn's horn to activate the spell

Beast of legend, myth and lore,
Give my words the power to soar
And kill this evil, evermore.
