I haven't really tried to explain the Gate to anyone else. It was just...I only go there when we do Human Transmutation. This white space that's just empty except for us and Truth, this white figure. And Al, Al's body is there, with his Gate now. I just have to figure how much, what to give up in exchange for it. It's because of the Gate that I can do alchemy the way I can, without needing to draw a transmutation circle. I guess in a way this Drift is sort of similar in terms of knowledge?
