Ephraim ti Horn is one of the four narrators in Iron Gold, the first of a new trilogy which takes place ten years after Morning Star.
Once a loyal member of the revolutionary Sons of Ares, Ephraim ti Horn lost everything in the Rising, including his husband, Trigg. In the years since, Ephraim has had no choice but to turn to a life of crime in order to survive, but when a dangerous new client hires him for the heist of the millennium, Ephraim quickly realizes he is in over his head…
After his fiancé Trigg dies, Ephraim works for the Sons of Ares. His men are captured and skinned in front of him. Virginia pardons the Gold responsible. This makes Ephraim hate the new republic.
Ephraim becomes a high-end thief who steals for brokers. He lives in Imbrium City on Luna, and his only friend remaining is an Obsidian.
Ephraim is, on the surface, a very rough and closed off person who does not seem to care about anybody, even himself. Eventually it turns out he cares deeply about several people such as Volga and Trigg. Trigg's death left him depressed.
Ephraim has a bad leg.
