One

One is the leader of the Rippers, an organization responsible for almost all the grief Calliope deals with these days.

Alia/Aliases: Iron Henry/Henry Ironheart, Henry Clerval, Henry Jekyll, Henry Gale, Hyde, 'The Broken Piece Man'

One is a results-oriented psychopath determined to reboot the Universe and start it up again without pesky Death getting in the way of things, no Muses, no Writers, no...nothing that bothers him because all of that stuff is wrong in his mind/s.. It is possible he lived in a more stable form with his blended personalities in the past, but by his own admission, the battle between Jekyll and Hyde pushed Hyde into asserting dominance over the other personalities.

The Many Faces of One
Iron Henry: A character in one of the tales collected by the Brothers Grimm. Torn apart by grief at the deaths of his closest friends, he let in the Shadow and protected him until he died. The Shadow still feels kindly to Iron Henry...at least, he sounds like it. We're not completely sure. The Shadow is not exactly a bastion of sanity.

Henry Clerval: This Henry is an interesting variation of a Namesake; he was the best friend and foil to Victor Frankenstein. Mary Shelley was the Writer who created them both. Without Henry Clerval, there would not have been a Victor Frankenstein. Henry Clerval is an intelligent, nurturing peacemaker with the ability to bring out the best in others. Frankenstein's Monster murdered him.

Henry Gale is the same Uncle Henry of the Namesake Dorothy. He and Aunt Em lived in Oz with her until Aunt Em died, seemingly walking into the Deadly Desert (this is so far unproven, but dreadful). Out of respect for his deep grief, Ozma gave Uncle Henry the power over plants and wished him well on his return to Earth. The control over plants seems to be a part of One's control at Bramble Manor. The little house in the middle of the wheat field in Kansas where One plots Machiavellian schemes appears to be Henry Gale's old farmhouse. It is hard to reconcile the gentle, quiet and peaceful farmer of L. Frank Baum' s writing with a part of One's personality, but Adora says this Henry Gale is unlike the one she knew, and could have been corrupted by a Shadow.

Henry Jekyll is a Namesake from Robert Louis Stevenson's The Strange Case of Dr. Jekyll and Mr. Hyde. In it a well-intentioned man creates a serum to release his inner, uglier self out as a sort of catharsis--only the uglier self (Hyde) is impossible to contain. Eventually Jekyll admits he can no longer control him, and people are dying from his hubris. He allows himself to die, taking his divergent Hyde personality with him.

One uses Henry Jekyll's face. He is a seemingly youthful, smooth-faced man with a strange...uh, thing on his left forehead like a leaf or a crystal, or a crystalized leaf...well, it looks wrong to be there. In one of those weird twists that happens in the real world of fiction all the time, Robert Louis Stevenson came up with the name of Jekyll after a man he knew: the brother of a horticulturalist and landscaper. The Bramble Manor of One's address looks very much like one of Jekyll's themed gardens. Hyde carries the same name as the monster in The Strange Case of Dr. Jekyll and Mr. Hyde. It looks like The Shadow calls itself Hyde--perhaps it was the actual freed personality within Jekyll, or the name 'Hyde' was a pleasing wordplay for the monster hiding from plain sight.
