I've never tried Revenant but I'm curious about its lore. According to the wiki, the Revenant profession was 'introduced to the world by Rytlock Brimstone in 1328 AE who in turn learned it from Glint (...)'. Since Glint is dead, I'm assuming Rytlock is the only one in Tyria who knows how to become a Revenant. Is this correct? If it is, that means that future Revenants would need to learn the profession from him? Is it possible to teach the profession to someone? Or is that something that each individual needs to learn while in the Mists? I mean, it can't be that 'easy' to become a Revenant, if it took so long for the first Revenant to appear, and not even on his own, but with the help of Glint.
So my main question is how one becomes a Revenant after Rytlock. Thank you for your inputs
