Auregana's monitoring array was the first to sound a shrill alarm.

The biological signal readings across the global oceans surged wildly at an unprecedented rate. No longer were they the chaotic echoes of individuals; they had fused into several vast, unified Hive Minds radiating pure malice.

At the same time, the Tyranid Biomass deposit deep within the Deep Blue Sea Cave released astonishing energy fluctuations, as if an evil heart beating in the abyss had reached the peak of its contraction.

"Warning: Tyranid Bio-Ship-level biological signals detected. Multiple supermassive targets are rising from the deep sea, their trajectories directed toward this island and the coastlines of the major continental plates."

Auregana's synthesized voice was cold and urgent, drowning out every background noise in the command center.

As if to confirm her assessment, the entire island began to shake violently. It was not the tremor of artillery fire, but the horrifying geological groan caused by some ancient, primordial force stirring the continental shelf.

They were covered in thick, slick, ever-growing Chitinous Exoskeletons. Their shells were riddled with hive-like holes, from which endless Gargoyles and Spore Mines erupted like pus, instantly blotting out the sky.
