Hexis: Tyranids come under pressure

 The tyranid threat on Hexis had remained largely quiescent for over a year, as they had tried to rebuild their strength before launching a new offensive to overrun the other forces still in place on the dead world. In 10.021M42, there were signs however that the hive mind was re-awakening, now invigorated by some initially unknown force. Gradually both the eldar and imperial intelligence became aware of the emerging threat from the Tyranids on Hexis, dubbed "hive fleet R'lyeh" by the Imperium.

For years the tyranids on Hexis had been little more than an annoyance, with no hive fleet and no unified hive mind to guide them. During this time the psychic force of the alien species had been signalling to others of its kind, intending to either summon a hive fleet or gain enough biomass to overrun the world and convert it to the production of new hive vessels to begin a new migration.

The result of this was the arrival of several spores from other hive fleets over time, and now "R'Lyeh" was something of a hybrid of genetic stock, and growing in strength by utilising the organic materials of the very rocks of Hexis. In late 10.021M42 both the Aeldari and Imperium launched their own pre-emptive strikes on the Tyranids. The astartes of the Iron Roses chapter engaged in a minor raid to gather intelligence, while the eldar appeared from nowhere, striking at a hive node they had identified in the deep desert of the planet. This caught the alien race of balance, forcing them to respond, and the general increase in violence elicited a response from the orks on the world as well.

As the eldar corsairs were destroying the hive node, the orks around Menthoteph became energised and, always looking for a fight, launched their own attack against the xenos race, attacking with unbridled glee and removing the tyranids from around the city. Whether this was forseen by the eldar is unknown, but the result was to effectively reduce the threat of the tyranids on Hexis, at least for the time being, clearing them from key positions around the important necron tomb complexes and keeping the hive mind at bay for now.
