Raven (Pandora Hearts)

Raven (Reibun, lit. Crow) is one of the Black Winged Chains which act as the guardians of the Doors to the Abyss. Previously, it was necessary for each incarnation of Glen Baskerville to form a Contract with Raven and his fellow Black Winged Chains, though following the fall of the Baskerville Clan after the Tragedy of Sablier, the Door which Raven protects was given to the Nightray Dukedom alongside the establishment of the Four Great Dukedoms. Raven has since been unable to form a Contract with anyone for close to 100 years, as it had already bonded with Gilbert Nightray prior to the Tragedy - though because of Gilbert's release from the Abyss, Raven eventually forged his fated Contract with Gilbert. When Jack Vessalius attempted to drop the world into the Abyss a second time, Gilbert severed his Legal Contract with Raven, instead forming a proper Baskerville Contract which was kept in place for another 100 years afterwards. It is likely that after Gilbert's eventual demise, Raven will return to serving under Leo's successors.

Appearance
Raven's overall appearance is very similar to that of an actual raven, albeit being of size that is comparable to a house. The feathers and flesh around Raven's face appears to have deteriorated, exposing Raven's skull, leaving the only whispers of life in Ravens face being Raven's tongue and the tiny beady eyes in Raven's eye sockets, that are rarely visible due to their size and depth in Raven's skull. Raven is also known to have a round body with rather short legs that end in three-toed talons and a tail composed of numerous disorganized feathers.

Unlike regular Ravens, Raven is known to have two sets of wings, although the reasoning for this extra set of wings is unknown. Despite having so many wings, Raven may lack the ability of flight that Jabberwock and Gryphon are shown to possess because of the numerous lines of Chains that wrap around Ravens mouth and extend elsewhere around the area, with one holding Raven's mouth open and at least four other lines of chains criss-crossing around Raven's body.

Personality
Much of Raven's personality is gathered from the few scenes shared between it and Gilbert, leaving room for other possible characteristics that had yet to be shown. Raven is seemingly apathetic, rather blunt and brutally honest when spoken to, choosing to be straightforward with its own opinions. Despite this Raven is loyal to those it is contracted with, following through with any orders given, such as when Gilbert asked for their link to be severed even though it would cost its contractor his arm and Raven sent back into the Abyss.

Abilities and Powers

 * Raven can pass judgement on those accused with a sin. It would then open a path to the Abyss and summon the Chains of Condemnation in order to drag the offender into the depths of the Abyss. This is an ability shared with its fellow Black Feathered Chains.
 * Raven can create blue flames that can hurt the Baskervilles due to their connection to The Five Black Winged chains of Glen Baskerville. It is assumed that the Baskervilles could also be killed eventually with these chains. Raven has displayed that it can send out flurries of feathers at its opponents, which it can also set fire too.
 * Sealing Powers - Gilbert uses Raven to seal B-Rabbit's powers.
 * Teleportation - It has the ability to traverse various dimensions.
 * Illusions - Raven can create large illusions of menacing eyes, as it was shown to not have any eyes itself, but to intimidate its victims. Raven can also manipulate darkness to seemingly become one with it.
 * Raven shares the ability to mend damage to the Chains that hold the world together with his fellow Black Winged Chains.

Trivia

 * Raven is likely based off of the monstrous crow mentioned by Tweedledee and Tweedledum in Through the Looking Glass and What Alice Found There. Although never seen, the monstrous crow was feared greatly by the Tweedles, which could explain the feud between Gilbert/Raven and Noise/Duldum.
 * Another source of Raven's inspiration could stem from The Mad Hatter often asking Alice how a raven was like a writing desk in Alice's Adventures in Wonderland.
