Verglas
As the wagon began to pitch her off to the left into the abyss, Verglas grimaced. She had spent a long time designing that box and getting it just right, and now it was going to end up in a heap of splinters at the bottom of this stupid mountain. Also, she might die. But mostly, the box.
With a petulant tone, she gestured and mouthed two words of power. There were times when her obsession with the elves of old got her into trouble, and times when it was the Father's greatest blessing to her. Because, say what you would about their ancient oppressors, they had style.
In an instant, she doubled in height. Around the straps of her pack, a pair of magnificent white wings sprouted, unfurled and caught the violent updraft pitching up the mountain. It took Verglas a moment to stabilize, well away from the slipping wagon.
Sorry, box.
Spoiler: OOCStandard action to cast Alter Self into an Avariel elf.She really does specialize in ancient elven lore!
Move action, get the heck away from the wagon.
