That's what I'm worried about. I can't be on both the main jaunt and the walkabout at the same time, even assuming I don't vanish entirely, or fall into a liminal dungeon. If it starts showing up again and nobody else is looking, we might not even know it's around.

Leonardo taught me, and I know he taught some others. I've taught a few more, and am willing to teach anyone else who wants to learn. But some of the people that have been taught have already vanished. Right now, I'd guess there are no more than five or six people with the ability.
