Thank you so much for your kind words. You've made my day.
I should have said "the first reset occurs immediately after meeting S4vant." I'll have to fix that. Or, I'll just change it to "while" as you suggested, since I don't have the space.
It was my intention that it wasn't time that's being reset, just how reality is currently structured. In my head, the remaining colonists are just resigned to their fate (except for Phin) and have kind of just shut down. They've all seen hundreds of bizarre and horrifying things happen and they've even been hurt and may have even 'died' before. But, now that you mention it, I think 3 weeks is probably too long, so I will shorten it.
Thank you again!
