We do not know its motives, or its goals. All we know is—it’s wiped out civilization on this ring before, many times. When I went with Flurry Heart, we saw one city like that, filled with dead ponies. The natives are as much captives here as we are—we have no reason to suspect Harmony wouldn’t have total knowledge of all that transpires on this ring. The instant it decides to kill us, there won’t be anything we can do.”
