Rukia inclined her head in thanks. She knew she hadn't been part of this world for very long, so she didn't have any rank or authority to her name, nor had she dwelled long enough to garner trust (in her opinion). If he was willing to do this based on her suspicions alone, then she was very grateful. "I will feel easier knowing the Crystal is well protected. You have my sincerest thanks."

As he spoke, she spooned up a few bites of stew, dipping a chunk of crusty bread into the creamy broth. The air got thin? That was information she hadn't known before. Hm. How did one transport breathable air, then?

"This is true. There does seem to be a spell for everything. I don't know a way to transport breathable air, however." She glanced out the window, trying to puzzle out a solution. "The sooner we go, the better, but I have no wish to endanger you or your horse."
