ok official ruling plz... can our setting be an isolated location aside from an island? like a sealab or mountaintop cave or nuclear fallout shelter?
same concept and restraints, and adds a bit of variety and creativity?
or perpetually airborn supersecret flying fortress a la Nick Fury: Agent of S.H.I.E.L.D. except with all the heroes and villains DEAD save for you. also the controls are destroyed and it's powered by the sun, so that's why you're perpetually stranded. i still can't explain the conversational friend tho but that ****'s on you.
