Nibbles and Tillin

Supplemental-

Nibbles T. McGibbles is the name of a gnome who was a traveling companion and friend of the party before Kaszuk joined. The group said that they had saved him from a man named Tillin, a former foe of the party's. Nibbles needed a safe escort to Trifid City and offered his skills as an alchemist in exchange. By the time Kaszuk had joined them, however, Nibbles hadn't produced a single potion and instead was obsessed with his small pet lizard, Mumbles. He would keep mumbles trapped in a small box when not gripping him in his hands. He also gave off a magical aura of unknown origin.

With his mistreatment of his pet, his inability to produce even a single potion and frequent strange behavior Kaszuk quickly developed a dislike of Nibbles. Using his Speak With Animals ability, Kaszuk was able to communicate with Mumbles, eventually freeing him to the protection of Mareg. Days went by with Nibbles still failing to produce a single potion.

Eventually the group landed in Qur'rok, Zorak's home. On their first night all but Nibbles were invited to spend the night with the Gargalgrog Clan. In the middle of the night Nibbles snuck into the room in which they were sleeping and attempted to steal Mumbles back from Mareg. He failed and Mareg sent him back to the wagon to sleep. In the morning, Nibbles was caught sleeping on top of Mareg.

Once the initial shock and confusion passed Nibbles explained what had happened:  Apparently the group never killed Tillin. He was somehow able to trick them into believing that they had, turned Nibbles into a lizard and took his place. With Nibbles having been separated from Tillin for so long the spell effect wore off turning him back into a gnome. Quickly Kaszuk and Zorak ran to the wagon to try and catch Tillin but he had already fled. With the Qur'rok Tar tournament starting in a few hours the task of tracking down Tillin was left to the Gargalgrogs while the party took part in the ceremonial hunt.

It seems Tillin has escaped, to where, we do not know.
