My name was discovered long ago by Eldar Farseers in a captured library, that itself contained lost knowledge laid down by the Eldar from since before the Fall. It was during a cataclysmic battle between an Eldar swordwind host, and the 1st company of the Blood Angels of Sanguinus. It was during this conflict that the Thousand Sons traitor legion, came through the warp and made battle with the two as they fought like gods trying to keep the Library in their posession.
I just a young Guardian at the time, was an escort for the Farseer Inyaldir. And while he labored with the ancient psycho active sheilds protecting the long lost lore. A Chaos Scorceror named Medgiddo crashed through the security gate that our Bonesinger had placed over the chamber's entrance.
Ambushed, and labored. My master Inyaldir could not turn away from his task of securing the lore for Eldar hands. So my fellow Guardians and I had to face the warp spawned wretch alone. My brothers began to fall left and right, and I was but one of the three left to defend my master. With a battle cry to Khaine the war god. I lifted up my shirukein catapult, and rushed towards the scorceror. Shards of psycho metal flew from my weapon, though deftly they were swept away by his evil power. He then summoned warped horrors. And I began to tire.....But with one last bold charge I danced about the horrid creatures and casting volleys of shards into the flesh of the beast I was able to bring the warp fiend down, and as its shredded body collapsed. I turned my gaze to the Scorceror, as he began to walk towards my master. I could not stand by and let the fiend kill him, and take the lore. So I activated my fleet of foot, and blazed towards him with my knife drawn high above my head...And with a single swift strike I stabbed at the only open spot in his armour.....And down he fell in shock at his pain....And before his space marine body could defend itself I stood upon him and with my shirukein catapult spent all of my rounds into his mutated flesh.
When my master completed the ritual to bring the shield down, he lifted out of the container...a single book. And in its pages were detailed accounts of pre-fall lore. And in its hallowed scripts the name Elenai was found, meaning "The Star Of Judgement". And my master gave to me the name as a reward for my duty. And with the rest of the Eldar forces we left that Asuryan forsaken planet for good. Until a chaos gate was discovered buried deep within its twisted crust...........
