Rieya

Rieya, along with her sisters Drusilla and Solaria is a suspicious female monk who can be found in the area outside Serpent's Fang Keep in the time of Ultima VII Part Two.

Description
She can be met outside the Abandoned Outpost in the past of Serpent Isle, and like her sisters is set on 'aiding' the Avatar, although the quality of this aid is somewhat dubious.

As with her sisters, she is killed by the Avatar when it is revealed that she worked for the Guardian in attempting to prevent the planting of the Silver Seed.
