Ovarlis a young imperial system has recently fallen under the shadow of the hivefleet Jormungandr. The defenses in the Ovarlis system where easily overrun. The hivefleet launching millions of Tyrannocytes to drop billions of small tyranid organisms.
During this assault the hivefleet scouted the planets and met little resistance. Soon after it started to harvest the system for its biomass.
During the initial stages of the harvest several imperial cities managed to send distress signals. These signals were recieved by a company of space wolves called the Wyrmslayers. These wyrmslayers responded and soon tore a bloody path of vengeance through the tyranids. Having deployed their full forces and facing mostly smaller tyranid organisms the wolves quickly liberated several cities. It seemed the battle would soon be a "mop up" operation for the Wyrmslayers.
Despite the succes of the Wyrmslayers the hivefleet moved in its ships. Having spent little biomass in their initial invasion and having harvested great ammounts the hivefleet responed quickly by cutting off any and all escape routes the wolves had.
The Wyrmslayers are scattered in the system and face dire circumstances. As more and more bigger and powerfull tyranids are being sigthed, How will they fare?...
