An Akademiya researcher in Sumeru just showed me a fascinating discovery - ancient runes that suggest the elemental reactions we take for granted might follow mathematical patterns beyond elemental theory. Meanwhile, a Fontaine inventor is convinced she can replicate elemental energy through purely mechanical means. It makes me wonder... what is the fundamental nature of vision powers in Teyvat? Are they divine magic, advanced science we don't yet understand, or something else entirely? What theories have you encountered in your travels?
