Isarion Stormsmourn
Isarion Stormsmourn was the Exodite Prince of Ephraeleon, when it was invaded by Tyranids. As the invasion began, Isarion raced to warn his Father of the attack, but was left injured and unconscious after being ambushed by a Ripper Swarm. It was then however that his lover Una Belphoebe, an Outcast Ranger of Craftworld Iyanden, found him. As she called his name, Isarion briefly regained consciousness and pleaded with Una to warn his Father of the Tyranid invasion, so that he could rally the Exodites to their world's defense, before falling unconscious once again. Una however knew it was too late to save Ephraeleon and its people, as she had been warned by Farseer Kelmon Firesight, who had received a vision that foretold Ephraeleon's demise. The Farseer's vision had also showed him though, that if the Prince could be saved he would go on to become the leader of all Exodites and would ensure their survival in battle against any attacking Tyranid Hive Fleets. Seeing the value of what Isarion would become, Kelmon had charged the Ranger with bringing the Prince back to Iyanden and, though she knew she may earn his eternal hatred for doing so, Una picked up Isarion and ran back to the safety of a Webway Portal; that had delivered her and a small group of Rangers to the now doomed world.[1]
