Pothos

Pothos runs the apothecary of Moonshade on the Serpent Isle.

The Avatar first met him in Ultima VII Part Two when he stormed into the already spoiled banquet, reporting to the Mage Lord that he'd been unable to collect Blood Moss, which angered him.

Meeting him later in his shop, Pothos told the Avatar that he wasn't an important enough mage to sit in the council, so he ran a shop selling reagents and magical objects. He was worried that the Mage Lord would throw him into the Mountains of Freedom for this failure. He also mention Batlin trying to obtain Serpent Teeth, the gargoyle Palos, and the dangers of Stoneheart, which he had been tasked with buying to remove from circulation.

However, Pothos seemed to know a lot about Erstam, the "Mad Mage", including the things he did on the Isles of the Mad Mage. When Bucia told the Avatar that Pothos looked a lot like Erstam, the Avatar confronted Pothos him with this. Pothos admitted that Erstam was his father, and when the Avatar told him that they had to speak with him, Pothos offered a deal: Blood Moss for the way to reach Erstam.

The Avatar managed to retrieve blood moss from the southern swamps, so Pothos revealed how to summon the turtle that would bring the party to the Isles of the Mad Mage and added the password to give Erstam, so that he would speak with the hero.

Later, when Shamino the Anarch conquered Moonshade, Pothos was killed by crossfire resulting from the duels between the mages.
