story hooks	A Pale Sump Rat colony has abandoned a section of tunnel it has inhabited for decades. Underground community members are treating this as an emergency warning, but surface authorities are dismissing it. Something is wrong with the chemistry down there, and no one is investigating. Helix Biosystems has been quietly paying premium rates for live Pale Sump Rat specimens — specifically breeding females — through a chain of intermediaries. The chemical tolerance mechanism they're trying to replicate has a human application that isn't in any public research filing.
