Fistandantilus

Fistandantilus (? PC - 39 AC), also known as the "Dark One", was a tall, slender man with a long, iron-grey pointed beard, thin bony hands, broad shoulders, well-built body. He always wore his plain, midnight black robes in plain sight, and was the most powerful Black Robe of his time. He always radiated cold, and when he would stand in one place for too long would actually kill the grass and other plants in the immediate area.
Fistandantilus owned a castle, but would stay at his personal apartments in the Tower of Wayreth. He never claimed a friend other than his magic, but was a very good player at khas. At the height of his power in Istar, he knew every language, custom, and lore of all known races on Krynn. He thought it beneath him to own a staff or even to have a familiar. The archmage was able to travel anywhere on Krynn in the blink of an eye, and was used as a bogeyman by parents to scare their children. However unlike most bogeyman tales, his powers were all very much real. He even wrote a book Observations on the Structure of Reality.
In 39 AC Fistandantilus, with his allies Denubis and Pheragas, led their army into Abanasinia. When they arrive they discover two groups, the Plainsmen, led by Darknight, and the Neidar dwarves, led by Reghar Fireforge. Both groups wanted to join Fistandantilus army for different reasons. The Plainsmen were driven by greed while the Neidar wish to avenge their honor. Also both groups needed food for the upcoming winter and believed that the mountain dwarves were hoarding it.
That same year the combined army of Fistandantilus marched towards Thorbardin. Fistandantilus used the emotions of both the Plainsmen and the Neidar, and planned on abandoning the army to journey to Zhaman. Before he abandoned them though, he cast four major elemental spells. The first was fire and the second ice, which trapped hundreds of fighters in battle. There was another water, or storm-based spell that would get trapped by Spellbinder. This spell would not trigger until after Chestal Thicketsway took the spell, which was in the form of a glass ball named Zap away from Spellbinder. The fourth spell was never known.
There he would find the portal, and with the assistance of Denubis they would enter the Abyss. This was not to be though. A gnome named Gnimsh was present, and he triggered a device the interfered with the spell Fistandantilus' was casting. This caused a huge magical backlash that detonated Zhaman. The two dwarven armies that were battling outside were caught in the explosion and killed. Zhaman would be renamed to Skullcap.
