Jean Bodin
The name, Cherubina, was taken from the story "A Secret Of Telegraph Hill" by Bret Harte. The last name, Gabriak, was derived from Gabriakh, the name of a toy, a wooden imp, presented by Voloshin to Elisaveta Dmitrieva. Voloshin found the name Gabriakh in the book "Demonomanie des Sorciers" by Jean Bodin, where it belonged to an imp, protecting people from evil spirits.
