[@Tyki]"I used to once possess a weapon capable of annihilating such a swarm. It was a sentient virus that infected not the body, but rather the soul and mind. An intangible curse that was passed on through thought, and erased beings from existence. Any time a being would think of another, the plague would spread. If introduced to a hive mind, it would instantly slaughter every single member of their species across the Multiverse." He smiles, as he leans down on the table. "Of course, this weapon is hidden deep within Ygdrassil, and I might require some help retrieving it. I believe this is the only weapon capable of truly dealing with the Tyranid threat, as they will inevitably adapt to whatever is used to stop them. After some time, I have no doubt they will become resistant to magic, and even create new forms capable of hunting down magical beings."
