Sans what is Gold magic?

He looks confused for a moment, his brows lowering, before realization broke over his expression.

“you’ve been talking to aliza. she calls my justice trait gold magic, though it’s far from it, or the beautiful thing she thinks it is.”

He looks troubled, tapping his claws against his leg nervously.

“she has the capability for it too. it’s a rare kind of magic- in my lifetime, i only ever met one other monster that had it, and they fell when i was very young. it’s… a burden. its the last thing i want her to concentrate on, especially down here. the sins of the souls that surround her here… it would only hurt her. i’ll teach her, if we get to the surface. just… not here. not now.”
