Tessa's father is an Eidolon Greater Demon, specifically a fallen angel.


Sent by Axel Mortmain, this demon took the form of Richard Gray and slept with his wife, Elizabeth. Because Elizabeth was unmarked and through Mortmain's intervention by protecting her with the angel Ithuriel in her clockwork pendant, their offspring survived birth, resulting in a new kind of being: Tessa, a half-demon, half-Shadowhunter.

Tessa only ever heard about him from Mortmain in 1878, when she was sixteen. Before then, Tessa grew up thinking her father was Richard.[1]
