Declan's Corrective is a former member of the New Earth Hegemony who is currently a prisoner in Contrition's Figure.

Corrective personally killed 27 Divines, the last of which was Contrition. He has been in prison for at least 200 years, but has never felt the regret for his actions which would allow him to go free.

He is also a poet, and his writing apparently has special Mesh-affecting properties. One of his poems is Second Street Drifting, featured in the episode which shares this title.

He claimed that he chose his name due to his determination to correct the wrongs of his father, Declan.
