Zoranthus

Zoranthus is a very powerful mage on the world of the Pits of Carnage who has remained civilised and tries to find ways to fight the Guardian.

Zoranthus became disgusted with what the Guardian had done to his world and so wanted to find ways to battle the evil megalomaniac. Retreating into the deeper levels of the Pits of Carnage on choice was a smart move, since the Guardian was very unlikely to look there. Starting to do research into other worlds, Zoranthus found out much about the Guardian's empire and the mechanics of travel between worlds. He also devoted his time to study Air Djinn and even managed to catch one in a special Djinn Bottle.

The Avatar first heard of him in Ultima Underworld II, when a message from Bishop (given to him/her by Garg) mentioned Zoranthus.

After finding Zoranthus in the lower levels, the mage recognised a fellow enemy of the Guardian and spoke about his world's past, how the Guardian had taken away all the honor and laws in their world, so that it descended into barbarism, creating an endless supply of soldiers for his army. He also explained the workings of travel between worlds and revealed the surprising fact, that even the Guardian's resources were limited and already stretched thin.

When the Avatar asked for the Djinn Bottle, Zoranthus offered a deal. He would give the bottle for a Scepter of Deadly Seeker. After he later got said Scepter, he gave the Avatar the bottle together with explicit instructions what to do to capture the Air Djinn in his/her body.
