Yes, hearing and how Tahaan senses the sound are completely different things. He does not have the faculties to "Hear" but he can sense all the changes in his own way, and hear is the best word I could come up with :P

I like building worlds, and if you wanna map what we make out, I'll say go ahead. As long as you don't ask me to be exacting in my square mileage, my using vague numbers as reference for most things since math kills my head. I like going into intricate detail about certain locations, quite often just throwing in "There's a row of mountains" then when our characters are there, sculpting them out and adding the caves and fissures and stuff :P I don't mind mapping the basic outlines of things, but I will request we save the fine detail until our characters are, say, actually traveling across the world on some adventure. I don't wanna lock us into anything then want to make some major changes later because the RP calls for it. . .So yeah, as long as we aren't going into exactly how high said mountain is, I'm good with making the world, filly and completely :P
