Thentis

Thentis is a farmer in North Britanny in Ultima V.

When talking with him in the fields, Thentis spoke only little about his work, but steered the conversation towards questions concerning the current state of things in Britannia. After the Avatar repeatedly stated that things were not going well, and gave the password of the Resistance, Thentis revealed himself to be a member.

Thentis excused himself for being so careful, and said to meet the local resistance cell at midnight at the well for more information.

Ultima V: Lazarus
In Ultima V: Lazarus, when the Avatar first met Thentis, he told the hero that he had to work long hours as a farmer. He also briefly talked about how he worked with his companions Joshua, Leof, and Vigil, but provided little extra information about himself. If the Avatar told Thentis that things had changed for the worse under Blackthorn's reign and provided the password for the Resistance, Thentis told the hero to go to the well in Britanny North at midnight.
