Sure, you can go through Dragonspire again, but it's a whole lot easier to simply cast teleport (or call of home, if Brimloch roon is still your last town).

Although, as I think about it, it might be possible to collect the various chests around the area and build a tower to climb up to the ledge. Missy may try that later...

Of course, going through the 'Spire gives the opportunity for yet more random encounters with nice-sized monsters. XP, here we come...
