[@Heat] So I have a question. Can your charcater teleport to ANY place, or does he need to know the place, or to have seen an image/model of it before, so he can do the. Apart from the wall thickness, and headache, does he have any other limits to his teleport?

[@Sagittarius] What do you mean by nigh undetectable? Is he going so fast he only leave afterimages? Or fast AND silent?
