Redcap

Redcap is a Sidhe of the Winter Court. He first appears in Cold Days.

Description
Redcap is a young male Sidhe who wore a red ball cap, and thus earned his nickname by Harry Dresden. He is an actual Redcap Faerie who claims that he is "The Redcap.

He wore a black leather jacket and what Harry assumed was a red Cincinnati ball cap. He had straight black hair and very high cheekbones. His smile was vulpine (fox-like) with canines a tad too sharp and large.

Redcap has two known companions: a Rawhead and a Snow ogre, which Thomas Raith calls his "lickspittles". His laughter hurts the ears. He also recognizes the changeling Ace as his son, for whom he claims no affection, since in this he is different from the other Sidhe. Redcap is Maeve's tool. She put him up to trying to kill Dresden.

Legend
Redcap would greet travelers in a friendly manner and then murder them horribly in order to freshly dye his cap in their blood.

Cold Days
