Well that is a pretty intresting quesiton there cavalier it's true I didn't took the time to devellop the fluff part of my army.
Well then let us get into it.
My craftworld is a personnal and original craftworld. I rescently watched an Anime called Aldnoah.Zero, a step away from the master piece if you ask me. And there is a sentence in there that catch my ears and heart. " Let justice be done throught the heaven's fall. " I kept the heaven fall part and translated the name into Tel'Quessir, I don't really know what it is but well. I like the sound of heaven in Tel'Quessir, wich is Arvandor. So there you go this is my Craftworld Names, Arvandor, the Justice of heaven. that sound a bit pumporous like this now that i think aobut it. On things I wanted to do when i started to play was to be able to say Make it Rain, like rain of bullet i mean. So that's going to be my guide line for this craftworld.
I have a few guide line i would like to use from the list choice perspective. I will go into them as we go through my Craftworld story.
From a geographic point of view, if i may say, My craftworld is lockated somewhere in between Baal and Honorum , not too far from the Perdian Gap. They are often facing against Blood angels and Chaos spacemarine, because they are right in between those two.
If I were to discribe my eldars, I would say they are a bunch of eldar that learned to fight and to use every resources at there disposal to stay alive. Faced with immense foes, such as Blood angles and Chaos army, pretty often they understood that they did not stand a chance when it came to fight in CC compared to bring down you foes before he reaches you. They develloped the Alpha strike and repositioning tactics, and learned to exploit them in every type of battlefield, be it human city or waste land of deserted world. That why the Dark reapers and Vyper are often core to the army. They can fire the opponnent before it get to close and in vyper case reposition on the other side of the fight if need be. When faced with unbelivable threath, the Avatar in the craftworld is woken up and send to fight with the banshee, if you can't gun them down, you just have to face them head on in a fight, after all you are not going to let them kill you just because they reached you.
There is also one things they came to understand. Air support Can be key. Their Autarch, the untouchable Ereden Ohta, is one of the Few autarch to have walked the path of the Crimson Hunter. As long as he is fielded, the Army must field at least one Flyers. Yet even if he walked the path of the crimson hunter, Ereden did not stop there and found himself with the warp spyder. He stayed very close to the temple he visited. Therefore if fielded, Ereden must join with a unit of warp Spyder.
There is one things to know, Ereden did not choose the Path of command, he was made into following it. Most eldar chose a path to keep there mind from wandering. But Ereden did not. He could not follow the righteous path of the eldar, and left the craftworld as an outcast, becoming a ranger. He saw countless battlefield and discovered contless beauty in the star. But one day he got take in by khaine grip. He had been touched by Khaine. As Khaine grip was getting tighter he nearly killed one of the member of his ranger crew. To save his friends and himmself he went back to the craftworld. When he arrived, on the dock was a farseer. Sulrista Arrno was a young farseer at the time he had just started walking on the path of the seer and still had some training to do. But as he was letting his mind wander in the infinity of space he had percieved the pain of Ereden's mind. While the ranger was traveling back from space the young farseer explored the future and while he was looking find that if Ereden followed the path of the Command he would be able to save an important number of craftworlder in an upcoming war (we are speaking about a few century away in the future there), rahter tahn taking the risk of letting this future disapear the young farseer chose to go and talk to the ranger, nearly getting himself killed in the process. The ranger's burst of anger at the eldar that was pretending to be able to tell him what to do, when he had chosen to leave the craftworld, nearly sent the said eldar straigh in space. Well in the end it did not happened by some kind of fortunately transport passing by, or was it really fortunately? Once calmed down Ereden listen to what Sulrista had to say and followed him to a warp spyder shrine. Left at the door with all his things and nowhere to go he had no choice but to step in. Here began his commander path. As predicted buy the young seer, soon after ascending to the autarch position, with the help of Sulrista, that had become a full fledged seer during that time, he defeated a space marine army that would have destroyed a enormous part of the craftwolrd if left untouched. There had begun the Jumping storming duo of Ederen Ohta and Sulrista Arrno.
And that should be ok for some background. I will had some more later on as things come in

what do you guy's think? I'm no good with story righting/ story telling, so forgive me on this.
Edit : just noticed it was more of a character explanation rather than a background for the craftworld. i'm going to rectify this soon

just let me put all my idea together^^ Btw you already met Ereden, and Sulrista is getting painted
