Huntress: from Richard Carpenter's Robin of Sherwood

Robin is summoned to Herne's Cave to meet the Huntress. Who is this new shaman, and why is Gisburne telling everyone that Herne is dead?

The Sheriff and Abbot Hugo plan to claim Fairfax Castle lands but, returning from the Crusades, Peter Fairfax wants to avenge his parents' death - which he blames on Robin Hood - and keep his ancestral pile.

With half of the Merries fighting injustice in Hathersage, will the other half be able to keep Sherwood safe and convince Peter Fairfax that Robin isn't a murderer?
