I do not know myself, but I am willing to try and learn. While I don't intend to go after your sister, if she tries something to harm me, the crew or break onto the ship, I would like a way to be able to defend myself and those around me. I've dealt with fire and lightning magic, though I know it's not the same as your bending.
