Tell me if this is terrible.
The general idea is that oil is from creatures that weren't just small shellfish and plankton, but large and nasty and perhaps alien. Maybe the dissembled remnants of a past civilisation, but SCP-1000 used a past civilisation recently…
The thing is, the way to find it out eludes me. Is there some device that returns things to their native state, so releasing the creatures? Or maybe the SCP is another type of nanobot that restores them.
Well, i'm unsure. Criticism, advice, etc. would be very useful.
