Nice job with the idea, I'd play it. I am usually just a character I've Dm'd once and I killed most of my players(the only one I didn't kill fled). Bad choice for me. But I have a suggestion: Try to say many different things to them, important info without giving it to them. Try to make them think of asking someone something or going somewhere to find this info(in your case maybe a temple to learn more). Roleplaying is awesome, it shouldn't just be fighting. Well, good luck:)
