Reworking an old story, Shattered, character info:

Shameless, an antagonist, who is Nightmare’s other half. Shameless, or just Shame, was created out of all of Nightmare’s negative energy after a deal she made with Nevermore. Shame then becomes a constant terror in Night’s life. Guided by Nevermore’s hand she aims to control Night’s half of their soul for they’re still connected. Despite being freed from Night she is neither free from her own emotions forced upon her or the Demon Dragon’s influence.
