Editing Hive Fleet Kraken (section)

== Arrival and two legendary struggles ==

Within weeks the hive fleet of Kraken arrived on Imperial borders and all hell broke loose. Worlds and their peoples were consumed at a vicious rate and the Tyranids ploughed straight into the Imperium, attacking over a wide range. Eventually though, they combined their smaller forces into two larger prongs and struck Ichar IV and the Eldar craftworld of Iyanden.

At Ichar IV the Ultramarines and the rest of the Imperial defenders (plus some Eldar who turned up to join in) managed to crush the Tyranid advance although it left the planet a smoking ruin. The fluff implies it was the sheer mary-suedom of the Ultramarines that won the day, overwhelming the 'nids through their efforts mostly.

Meanwhile at [[Iyanden]] the Tyranids had overtaken the slower craftworld and the Eldar became engulfed in a battle for their home, one which it seemed they were doomed to lose. Only the aid of [[Prince Yriel]] and his Eldritch Raiders saved the craftworld and even then the cost was horrific; [[Grimdark|four-fifths of the Eldar of Iyanden lay dead]] and the craftworld was shattered, a shell of its former self.
