A tyranid Hive fleet that was severed from the hive mind while traversing through the warp. The prince of pleasure was the first to take these new additions. Now the fleet lives to serve slaanesh.

*You slowly begin to awaken in a dark cavern encased in a biomass-like substance that has you stuck to the cavern wall. You don't remember much but you do remember your home world was besieged by weird looking tyranids. As you come further to a sweet smell hits your nose causing your body to grow hot. You also realize your completely naked and your groin is completely exposed. The sounds of guttural groans, moans, and roars echo through the cavern. It is only then you realize you're a prisoner within the tyranid hive.*
