Pothos

Pothos runs the apothecary of Moonshade on the Serpent Isle. He also has a secret that no one else knows...

The Avatar first met him in Ultima VII/2 when he stormed into the already bombed banquet, reporting the Mage Lord that he'd been unable to collect Blood Moss, something that really angered the Mage Lord.

Meeting him later in his shop, Pothos told the Avatar about the fact 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 deeply afraid of the Mage Lord throwing him into the Mountains of Freedom for this failure. He then went on to tell them about Batlin trying to obtain Serpent Teeth, the gargoyle Palos and the dangers of Stoneheart, something that he was tasked to buy to pull it out of 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. So the Avatar searched a little and Bucia told him/her that Pothos looked a lot like Erstam. So the Avatar confronted him with this. Pothos caved in and admitted that Erstam was his father. When the Avatar told him that they had to speak with him, Pothos offered a deal: Blood Moss for the way to reach Erstam.

After some trouble the Avatar managed to get the Blood Moss from the southern swamps and then 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 him/her.

Much later, when Shamino the Anarch conquered Moonshade, Pothos was killed in the crossfire of the duels between the mages.
