Nightingale

Nightingale is a Memory Keeper of the Garden of Recollection in the service of the Eminence of Remembrance, Velka. She is a memetic entity, i. e. a being that only exists within memories. She made a deal with Lirren, Valil, and K'rrik to exchange their memory of the opening of the Breach beneath the Arcadian Citadel with a memory she possessed of the first performance of The Song of the Nibelungs, which Aereth Shaw also attended together with Dr. Roland.
