Toph? Toph was fucking made for this. She'd shown up, just a tiny little thing dressed a little too girlishly punk rock for the scenery, but had since then proven her worth. She stomped around the woods on the hike like she owned the place -- going so far as to take her shoes off and hop around from rock to rock, usually having to stop and wait while everyone else caught up.
Now that they were in their little clearing, Toph dropped her pack aside, glanced around blankly (because there was no other way to do it) and then shrugged. She twisted her foot on the ground and created herself, straight from the ground, a tent made of two thick sheets of rock.
