Betor expedition finds Nemesis alive

It had been years since tyranid hive fleet Nemesis had ravaged the Zadoc subsector, consuming a score of worlds and arguably precipitating the Imperial collapse in the region. Inquisitor Huron was keen to re-assess the threat, as the xenos had not been encountered for a long time, and the imperium had all but written off the tyranids as lost in the void. Huron knew they hive fleet may have scattered, but likely lurked still in the depths of space between inhabited systems.

Inquisitor Vorushko was also keen to assess the Xenos threat, as her plan to create a buffer of dead worlds between the Tau empire and the remaining imperial controlled subsectors in the region depended on the denial of any inhabited colonies in the Zadoc subsector. Alpeh and Betor had been consumed, but if the tyranids had left the worlds the tau would be able to establish bases, and eventually colonies on the dead husks of the former agri worlds. This could not be tolerated.

Huron was given a division of Vannaheim guard and the assistance of the Sisters of Battle in his first exploration of Betor, once a prime fishing world now reduced to a lifeless husk, devoid of all life. Or so he thought. On arrival at Betor Huron was surprised to encounter a world with its atmosphere intact, and its seas remaining. Previous experience with the extra-galactic aliens had led Huron to believe the tyranids simply consumed the world once it had been pacified, but here this was not the case.

Landing on the world the Sisters of battle found a dead world. Bioliogical life had gone, but the tyranid process of consuming all resources had not been completed. Inquisitor Huron was unable to complete his investigations however, as no sooner had the imperial force landed, than they were attacked and overwhelmed by a horde of Nemesis warriors. The Xenos took heavy casualties, but the Sisters of Battle could not hold back the tide. Huron and his force managed to escape largely intact, but it was clear that whatever Nemesis was upto, they didn't want to be interrupted.
