You study the machinery, trying to understand the relationships of the gears and connections, when a realization comes over you: everything here is off because of a small error. Not, like, philosophically. Rather, everyone in this room is trying to fix the error and its effects on the other modeled space bodies, but in reality, it's all because of this tiny offset with the moon. With a strong push you set it into the correct spot and the solution propagates through the entire model as all the pieces fall into place. Around you, the commotion slowly stops as everyone looks to the astrolabe. It's perfect now. Suddenly the castle rises, and you rise with it. This isn't a castle at all, it turns out, it's a castle-y spaceship, and now that you've fixed their model of the universe it's setting off, its navigation path finally clear. On the downside, you for sure won't find your tent now, but on the bright side you're disguised as a raven and taking off on a space adventure in a flying castle surrounded by mysterious strangers, so things are looking pretty good overall.
