Greymarch

Greymarch is a fighter who'd been captured by the Oppression.

The Avatar found him in the jail of Yew in Ultima V. He'd given up all hope, especially since he hadn't heard of his son Froed in a long time. However, when the Avatar told him that Froed was well in Skara Brae, Greymarch gained new hope and told the Avatar that the Scepter is very powerful and to consult Sir Simon in Bordermarch.

In the Lazarus version, he actually is animated to break out, in order to join his son.
