The Harlequin Rook

"'Fairies are real, and they're a royal one. I've been hunting them for a while now.' - The Harlequin Rook, whispering to Rashaad at the Christmas Party about Warren's Fae nature"

Summary
The Harlequin Rook, also known as the Rook, or simply 12, is one of the 12 members of the High Court of the Fae, and the only current surviving member. They are the representative of the Eternalis Carnivale, one of the 12 provinces of the Land of the Fae. They constantly wear an outfit reminiscent of a Venetian Carnivale outfit, including a mask which covers their entire face and faecilidae.

History
Not much is known about their history before joining the Congregation, besides their service in the High Court of the Fae, and their planning rebellion against the former tyrant king. They attended the Christmas Party, where they - with Rashaad's help - took Warren and 2573 to the Land of the Fae, where Warren learned that they were, in fact, the rightful king of the realm. They then adventured to the King's Castle, eventually killing the Pustulous Mass and returning order to the land.
