First of all, I have to thank you guys because this idea looks very interesting!

Tiny questions about powers concerning this girl over here. I don't know if you guys are familiar with the AtlA/LoK verse, but this character, Lin Beifong, has a special skill of Earthbending that's called seismic sense. It allows her to use vibrations on the floor to "see" further than what she can see. Could she be able to keep this ability? Not only for her, but also in case her mother, Toph, ever shows up in game, since she's blind and this seismic sense is the only way she has to be able to see.
