Lol! That would be pretty awesome... too bad everything is covered in wasp nest crap and I don't think this building is constructed out of sheet metal. HOWEVER! When we find the payload at the top, maybe we can all just hop on top and ride that puppy back down outside! WOO! Unless... crazy maniacs outside decide it's a good idea to start sniping anything that flies outta the building... which they have already done, btw... Maybe ye ol dungeon crawl is the best way to go.
Remember that idea someone had to tie themselves to Devoted and have him fly everyone up that way? He probably wouldn't make that suggestion in character, but he would probably do it if everyone asked... That sure would be painful though... 2 humans and a dwarf tied on to a little teenager elf's climbing harness... He does have a climbing harness, though, so it's feasible.
I just thought of something. Devoted's crazy ass expensive comlink can communicate with our trans downstairs... mmm lol, I need to leave Yani in Europe. Too bad we lost etherial.
