Beryl

Beryl was one of the settlers to settle the Northern Forest of Serpent Isle. But after the murder of the other colonists, she became Draygan's personal slave.

When the Avatar met her in Ultima VII/2, she was desperate to escape her slavery and told him/her that she knows the Forest Master, and that the only way to stop Draygan would be with an arrow counted with the extract from the plant King's Saviour. The Avatar followed her advice to incapacitate and kill Draygan. Beryl, finally free, chose to dwell with the Forest Master rather than return to civilization.
