The Path of Kings
The Lady with the Green Hair
The Lady with the Green Hair, or Princess Nyrissa
The Lady with the Green Hair has been identified by the party as Princess Nyrissa, the illegitimate daughter of King Oberon of the Seelie Court and Queen Mab of the Unseelie Court. The fey overlords have imprisoned their unwanted child in the Fellnight Realm, a dimension of eternal twilight between the First World, the Shadow Plane, and the Material Plane. However, it seems that Nyrissa has found a way to send her minions to the Stolen Lands, through certain cracks in the walls that separate the planes.
