I'm planning to introduce in my campaign the notion of ascended master. Upon esoteric knowledge it can open a wide range of possibility as our world (real one) is rich on brotherhood, famous figures... which can be introduced in the game.
The idea is to find a process that permit to a human or metahuman to progress upon a path to change his state. We all know sentient astral being trying to come in the material world but this path is the opposite. Rappidly I try to bring a way to explain buddhas, lamas, saints, alchemists (I'd really love to introduce people like count of st germain...)
I allready sketched a few things about this path which I probably call : the path to enlightment (ref to vampire rpg I know

)
But I ask for some hints on how you would deal with the subject ?
Thanks
