Prince Yriel

Even other Eldar think this guy is arrogant. Let that sink in for a moment.

The swashbuckling, pirate prince of the stars, Prince Yriel Ulthanash is what you would get if you change Jack Sparrow to an Elf then throw in a bucket load of cocksure arrogance, a sense of hygiene and away you go. He is known as the greatest Eldar naval genius to have lived and this only makes his arrogance grow greater (and if other Eldar are calling you arrogant, then that has to mean something).

The prince was once an Autarch and the fleet master of Craftworld Iyanden, and was renowned for his tactical genius and daring leadership. It was a testament of his skill and ability at void warfare that he received the post of Autarch without having walked the Path of Command, but had instead walked the Path of the Mariner. He thrashed a Tyranid Hive Fleet and a Chaos Lord’s armada and his deeds made him well feared and respected. It was the chaos fleet that would be the turning point in Yriel’s career however. In his recklessness, he stripped Iyanden of all its starship defences and forced on defeating the enemy. A last torpedo fired from the chaos flagship burst through the fleet and made it through to strike the craftworld, inflicting huge damage and instantly killing many tens of thousands of Eldar along with destroying their soulstones (you know what the latter means).

It should come as no surprise that Yriel was stripped of his rank for his foolishness, which led to so many avoidable deaths. It was, however, a surprise to Yriel, who was so enraged he went into self-imposed exile and many of his men followed him. With these men he started the Eldritch Raiders, which became one of the most feared Eldar pirate bands in the galaxy behind Duke Sliscus and his Sky Serpants. Many believe that Sliscus is yriels dad, and the whole pirate thing runs in the family.

For years Yriel plied the stars, stealing from the rich, ignoring the poor, making raspberries at the Imperium who couldn't catch him even if he handed himself over to them (once the Imperium tried to estimate how many of their ships he had pillaged, Yriel trolled them by spamming a message across the Imperium that he'd gotten to many more ships than that). They tried to turn him against other Eldar corsairs, but this backfired splendidly when he just absorbed them and made himself an even bigger menace.

When Hive Fleet Kraken arrived in the galaxy, one of its tentacles was heading directly towards Iyanden, which could not outrun the speed of the Tyrannic threat. When Yriel heard of the danger his craftworld was in he at first ignored it but in the end, blood is thicker than arrogance, and he could not truly abandon his people. He and his raiders struck like the spear of Khaine against the Tyranids, tipping the scales in the favour of the Eldar. To save his people Yriel took up the cursed Spear of Twilight, which would doom it’s wielder, and turned it against the bugs, slaying the Hive Tyrant that lead the beasts (retcon'd by Guy Haley into the Swarmlord himself). Hailed as the saviour of the shattered craftworld, Yriel was reinstated as Autarch and master of the fleet.

Since then Yriel has fought many battles and feels his time is soon to be over. However a vision by the Harlequin Shadowseer Sylandri Veilwalker (who had earlier suggested to send the message of help to Yriel, was there when he took up the spear, and may or may not have had a thing with Yriel at some point) has shown him he still has much to do and the end times may be upon the Eldar. With a renewed spirit, Yriel steps forth to kick demon ass once more in the name of Iyanden.

He then stabbed the Hive Mind, well not really, but it as a whole yelled out in pain.
