===Overview===

In the aftermath of the Craftworld's [[Battle of Iyanden (Kraken)|original battle]] with Kraken, Iyanden's [[Farseer]]s had created a [[Warp Storm]] to block the Tyranid pursuit. Hundreds of [[Bio-ship]]s had been caught in the tempest, and the Eldar had assumed them destroyed. However this was not the case, and thanks to the prophecies of [[Taec Silvereye]], Iyanden learned that Kraken's remnants had been returned to the [[Materium]]. Worse still, it seemed that Kraken's remains were heading towards [[Hive Fleet Leviathan]], and the Eldar knew that if the fleets were to combine the results could be catastrophic. The Eldar bio-information that Kraken had consumed could be merged with Leviathan's resources, creating an unstoppable strain of Eldar-Tyranid hybrids. Thus the Eldar surmised to stop Kraken once more, this time at the world of [[Duriel|Dûriel]]. Iyanden was soon aided by [[Biel-Tan]] and surprisingly the [[Dark Eldar]] of [[Commorragh]] in their efforts. [[Harlequin]]s were able to broker this alliance.{{Fn|2}} The Dark Eldar provided the solution to defeating the Tyranids: triggering a psychic device called the [[Fireheart]] that would destroy the core of Dûriel and all the alien beasts with it. However it could not be detonated remotely, so the Eldar knew that whoever stayed behind to activate the device would perish with Dûriel.{{Fn|1}}
