Nightingale

Nightingale does not use his real name and never reveals his face, likely for a multitude of reasons. An enigmatic and mysterious person, virtually nothing is known about him.

Background
Nightingale's history is unknown. He has made only two appearances so far in The Madman's Verse both of them in a situation he controls, and always when he has places to hide himself. An agent of Nocturnal, likely keeping the realm in order is a task of his, which is why his goals' align with the group's. The mercenaries encountered him for the first time when investigating Dalacon's old laboratory, which he had been searching himself.

Personality
Nightingale is calm and controlled, obvious from initial encounters with him. He is also very cautious, judging with how he deals with the group. He also has a flair for the dramatic, shown by how he handles Hafnir.
