I find this fascinating. and I could imagine this inspiring many different great bits of D&D play. I'd hesitate to go the traditional "animated skeleton" route with such a jeweled skeleton, but if I did, the implications of a saintly skeleton being brought to life would be quite fun to play out. Or another route: how many players, do you think, would expect skeleton-venerating villagers to be anything other than generic cultists? Here's a chance to throw away the boring pulp-fiction "evil death cultist" thing in favor of something more layered.
