Getting Camp Nisus fixed would take more than singing and motivation on Bluebird's part - it would require work, the sort that needed her to kneel in the mud and pick splinters from her fingers as she set about the rough and surprisingly complicated business of rebuilding. She was no stranger to it. The way of such repairs were ingrained into her childhood, to the point that she felt she could repair a fence or roof with her eyes closed.
Back then, the latter had been more dangerous, but in Terrasphere she had no need to fear falling. Thus, she remained happily at work as she nailed shingles to the roof of a wooden hut, whistling as she went. It wasn't a grand adventure, but it was surprisingly relaxing...
Relaxing, that was, before a peal of distant thunder startled the young woman and caused her to drop her hammer, which knocked into her little stack of nails and shingles and sent them cascading downwards. She covered her mouth, feathers on end, as she slid down to the edge of the roof and looked down. Hopefully no one had been struck by the falling equipment.

Ah, I'm sorry! Is everyone okay down there?
