History
Aballister Bonaduce killed his wife long ago and left their small son, Cadderly, on the doorsteps of the Edificant Library to be raised by the priests of Deneir and Oghma. It seems that Aballister couldn't be bothered with raising his own child, as the boy would have stood in the way of his studies of magic and his ascension through the ranks of the wizards at Castle Trinity. Years later in 1360 DR, Aballister is the most powerful wizard in Castle Trinity when the forces there decide to begin their campaign of conquest. Aballister had spent the two previous years gathering the ingredients for the Tuanta Quido Miancay, the Most Fatal Horror, a legendary potion of Talona.s poisonous, evil power.

With the potion concocted, the chief priest of the Castle, Barjin, demanded the right to strike with the potion. He placed it in the cellars of the Edificant Library, where it caused all the people who breathed in its vapors to act without inhibition. Aballister's son Cadderly, now a priest of Deneir, defeated Barjin and plugged the potion. Castle Trinity's next step was to invade Shilmista Forest and destroy the elves there. Ragnor the ogrillon led the attack but also was defeated by Cadderly and his friends. Aballister then commissioned a group of hired killers from the Night Masks guild in Westgate to kill Cadderly, they too failed. Cadderly and his friends then took the offensive and traveled to Castle Trinity itself. There they braved many traps and battled the Castle's nearly infinite defenders until they reached Aballister himself. He and Cadderly then did battle with spells, and though their powers seemed closely matched at the time, Cadderly's spirit was stronger and he won the day, killing his father.
