I don't think they've been offering an event for free replay more than once and this event wouldn't be worth spending 500 gems to replay so replaying seems unlikely. Even if you someday replayed the event when you are in a higher region, you would find the gear too low to be worthwhile. I'm in Atlantis (still pretty early in Atlantis - working on the second god), and the Atlantis items are lower than anything in my camps. Even the Greek items are too low to benefit my Atlantis camp.
When I started in Atlantis, the Atlantis capacity item would have been lower than anything in my night camp and the regen item would have been only 5 higher than the lowest item I was using at the time.
Food or decorations for experience would be the best use of the flashlights.
I appreciated this event for the fun quick story line, the chance to stock up on wood, coal and some other earlier region materials and to get a jump start on some materials for Greece.
