D&D 5E What's in a temple?

[Wofano Wotanto]

Candles/lanterns/torches that were never meant to be lit by man. If a player lights one of these candles/lanterns/torches (hopefully all identifiable by a skull motif), then it triggers a soul-sucking trap as enervating black and purple energy begins siphoning all life within the light emitted by the candle/lantern/torch. Those creatures in the dim light radius have advantage on their saves.

Or invert that idea, and have miraculously ever-lasting lights in some places that are never meant to be extinguished. If the players (or the vagaries of combat) put one out, it opens the way for the unnatural THINGS that were being held at bay by the light...

Unusually love @Quickleaf’s ideas, but this one is even better!

Couldn't have done it without them. I'm better at riffing on ideas than coming up with my own.
