Heliton
Heliton was a Captain in the Emperor's Children Legion, during the Horus Heresy. Shortly after the Dropsite Massacre, Heliton was among the Legion's Brotherhood of the Phoenix who came to a meeting called by Captain Lucius and were convinced by him that a Daemon has possessed their Primarch, Fulgrim. Incensed at the idea[1a], the Brotherhood devised a plan to ambush the Primarch aboard the Strike Cruiser Andronicus when Fulgrim was due to visit the lab of Chief Apothecary Fabius[1b], and then find a way to force the Daemon to leave his body[1a]. However during the ambush, Fulgrim proved himself to be a deadly opponent despite being vastly outnumbered, and he mortally wounded Heliton. Though the Captain would survive to see Fulgrim captured by the Brotherhood[1c], he died from his wounds shortly afterwards.[1d]
