If you want to write about the incident itself, you're welcome to but I don't know if it's really needed right away, you could always filter in with flashbacks since it's just you translating information that we can't really use or reference (our character weren't there, I mean). I think on the second or third day would be fine. And for the easiest means, I don't see my characters living too far away because there's no point and it might just complicate things further anyway. In terms of the general group (us) meeting and combining forces, would we illustrate that in our first 1-2 posts?
