That's why they've staggered this one. Because you *can't* go in there alone and live, you'll get slaughtered. So they had to do it this way to make sure enough people would participate each time.
I was concerned about that too; when I missed it the first time, I was like, "What if the npc spawns again, I go inside, and there isn't enough players to clear the FATEs because of the odd timing? We're screwed!" XD
