Presto

Presto is a very small wizard living in Skara Brae during Ultima IV

Description
The diminutive Presto could be found at Sasha's Herbs and Spice shop, where he would freely boast about his ability to cast great and powerful spells, particularly Jinx, Kill, and View. Should the Stranger recognize that all of these incantations required the potent reagent nightshade, they could ask the magician about the rare fungus, and he would in turn direct the hero to ask Arron of the Axe 'n Ale in Vesper.

Trivia

 * In the Nintendo remake of Ultima IV (where most character names were omitted and dialogue was significantly modified), Presto can be identified with a fighter in Vesper, who gives the same information.
