Rebecca is going to Lunabella! It's weird but she wants to see cool things and be better-traveled and maybe it's less weird if you see it in practice, a lot of people do reportedly like it there.

So this she does, hopping out of the portal network, silk witch robes whispering against her skin and lovingly-conditioned hair tightening its curls in the light gravity.
