What the mosquitos can't kill, eat or destroy, they just encase in their vast swarm never to be seen again. In the middle of the mosquito sphere, in the most dense part, there the gods of old are caught and resting in an endless dreamless sleep. Only one, the ONE IN THE CENTRE dreams. He dreams of the end of days, he dreams of despair and insanity, his dreams can rip apart the planes and shatter reality. HE is the one who is never to be awoken, he is the core and the source of the swarm, but for those that look too deep into the darkest of secrets there awaits the shocking truth, for it is not the swarm that follows the DREAMERS orders, it's not the swarm that protects the DREAMER.
The swarm is a prison to never let the DREAMER escape. And it sacrifices everything to fulfill that task. Even if it means devouring everything in existence, because of the alternative would be even worse than that.
