The Journals of Sparrowhawk
Veiled woman - Part of the defenders of the caves.
A woman in a heavy veil. Distrusted by some at the caves but accepted by the leaders. Her motivations are unknown but it is believed she took part in the actions to retake the caves. Some dwarves were found turned to stone and the party made a connection between her heavy veils and this event.
We pretty much think she is a medusa – her hair beneth her hood is decribed as writhing.
