Chamfort

Chamfort is the blacksmith at the Arms of Justice in Yew in Ultima V.

When the Avatar encountered Chamfort and asked about the Resistance, he became suspicious. However, mentioning Terrance of Britain, whom the party may have spoken to previously about the Resistance, Chamfort came around. Knowing the Avatar had spoken to Terrance, he asked the Avatar if they would like to lend a hand to the Resistance. Upon accepting the offer, Chamfort directed them to see a fellow named Landon, the leader of the Resistance, whose secret hideout could be accessed through the fireplace in Chamfort's workplace.

Finally, the Avatar, now agreeing to aid the Resistance, learned of it's password: DAWN.

Ultima V: Lazarus
In Ultima V: Lazarus, Chamfort tells the Avatar that he thinks it best to stay out of government affairs, and willingly admits to wanting nothing to do with the Oppression. In fact, the Avatar later learns that Chamfort is highly involved with the Resistance via Terrance. Ronan tells the Avatar about the falling out between Tactus and Chamfort over working for the Oppression, and if the hero questions Chamfort about this, the blacksmith will request the Avatar send a message to Tactus apologizing for some of the things said between them.

Lady Guinere asks the Avatar to convince Chamfort to supply a shipment of weapons to help defend against an orc invasion that threatens Skara Brae and Yew. If the hero tells Chamfort that the threat is real, the blacksmith well provide the goods.
