If you don’t mind my asking, what communities?

I’ve slowly been finding even some of the more niche interests of mine that weren’t here when I first joined have slowly been appearing

Quite literally self ‘Annihilation’, I think the shimmer itself is more analogous to cancer (continuously expanding, with random distorted outcomes, most of which are agressive towards anything untainted by the shimmer), but fundamentally each of the characters are there for their own different reasons for self-destruction with the hopes that it benefits others, as they effectively know it’s a suicide mission).

The bit that I cannot recall if it was explained is why did the special ops guy go if he had a loving wife at home; what was his reason for self destruction?

I could see it helping with the ground floor but still neglecting the bedroom level, etc
