Leonos
Leonos was a Terminator of the Blood Angels First Company, who served under Sergeant Alphaeus as a member of Captain Karlaen's Honour Guard during the Cryptus Campaign.[1a]
Squad Alphaeus was part of a First Company task force sent to evacuate Governor Augustus Flax when Asphodex was invaded by the tyranids.[1a] Leonos was killed while the task force was awaiting extraction, when he was impaled through the head by a Tyranid Warrior's boneswords.[1b]
Despite not being related by blood, by some quirk of the Sanguination he was the genetic twin of Damaris.[1a]
