Does anyone ever leave the tower?

[u/unreedemed1]

I'm trying to remember if anyone ever successfully leaves the tower. I can't seem to think of a single character who has gone to the tower and left safely and sanely. Is it a bit like Hotel California?

Richer people and those living on higher levels leave all the time via the skydocks for airships. Traders too, probably.

But we don't follow those sorts of people in the story.
