Craftworld Iyanden is one of the major Eldar Craftworlds. It suffered heavily from an attack by Hive Fleet Kraken, losing four out of every five Eldar before Autarch turned Corsair Yriel managed to drive out the Hive Fleet. As a result, Craftworld Iyanden is forced to rely heavily on Wraith constructs to keep them afloat in combat, and half of the ones alive are probably Bonesingers. They suffered further when WAAAGH Rekkfist invaded the Craftworld and were nearly overrun when the Dark Eldar of the Kabal of the Wraithkind appeared from the Webway to save them. After the battle, the Seer Council inquired why the Dark Eldar had saved them, and they replied that they thought Iyanden's angst over using Wraithlords was so hilarious that they couldn't let them die. So grimdark.

According to Matt Ward (which is all we got since no one else ever went beyond the above paragraph) before they were NOMed they used to be the de facto leaders of the Eldar (you know being the "biggest craftworld" and all), having both designed means to harvest Soul Stones and the early Infinity Circuit. Due to having the resources and, at the time, a rather peaceful part of the Galaxy, they decided to rebuild the Eldar Empire. However, since most Craftworlds were either busying doing their own things, or didn't have the means, they could only get Biel-tan to join them.

Things were going well and the two fucked Chaos' shit up, even gaining new allies: the Ybaric Cluster Exodite Worlds and Craftworlds Malan'tai and Idharae.

But then everything went to Grimdark once they started fighting Hive Fleet Naga. Iyanden lost all its buddies as the Ybaric Cluster was isolated by a warp storm. The Invaders chapter destroyed Idharae and the Doom of Malan'tai as well. And to add even more grimdarkness, when Yriel went to battle with all of Iyanden it resulted in a Cyclonic Torpedo hitting the craftworld, killing a few thousands and breaking their soulstones.

And then, after the battle with Kraken, Biel-tan left them for dead because they're huge assholes.

The Craftworld that gets shit done

As a result of their codex supplement and being the most underused of the Craftworlds. They currently have the highest number of victories of any other craftworld, despite being best know for being 'Nid food.
