Bersimon
Bersimon, often referred to as The Weather Wizard is a weather wizard who lives in a tent on the cliffs of Citadel Island. He is a fully qualified wizard, who graduated from the School of Magic.
The Weather Wizard is the only one capable of chasing the storm that prevents Twinsen from going to Desert Island. However, he has to stand at a high point in order to utter a conjuration, and the lighthouse is the only available place at the island. After Twinsen freed Raph, the lighthouse keeper, Bersimon is able to stop the storm. Then, finally capable of landing, the Esmers come.
Bersimon also once hid Sendell's Ball in a cage of ice in the sewers. He already made a potion, which only needed a pearl of incandescence to become ready for use, for freeing the ball.
