Since the outbreak of a floating molecule- REKIDUS- the slowly dwindling population of Ferum- anthromorphic people- are hired as "Sky Lifters". Paid by the government to find a certain few Ferum that can breathe the air and kill them, since they carry the Red Disease, whether if they are freshly infected or to soon decompose from the inside out. Those who were not born with the immunity die in contact with any open oxygen made naturally. Whatever of society left is burrowed underwater safely in submarine cities, compounds, and anchor-tethered pods.

The Sky Lifters division is divided on specialty, like the ones listed below.

JANITORIAL TEAM - The half that go out to the contaminated surface and track, locate, and exterminate any infectious beings roaming.

ODDYSSEY TEAM - The other half that is closely alike to the Janitorial team, except sent in smaller groups like partners or quads to recover certain infected Ferum that could either hold the cure or be worth studying.

SKELETON CREW - Essentially the Janitorial team except only used for intense cases or hunts. Rarely are they sent out to surface unless absolute needed.
