Elementalist Skinline

In Elementalist Lux's trailer we were left with what seemed like a wrecked Demacia, having Lux and some unknown beast fight in the ruins of the former city. Nothing about that was explained, but maybe this could serve not only to get new skin lore, but also to expand the Elementalist skin into a line, the same way that it happened with Pulsefire. Lux is one of the youngest, but if she managed to evolve and control more elements... What about the rest of, way more experienced and powerful, mages of Runeterra?

Elementalist , , , , , , or even are just some of the many legendary mages likely not only to survive, but also master the elements in ways that Lux is yet to manage.

Be it as enemies or allies, all these mages in perfect communion of elements, not switching and getting stuck like Lux does, but being able to use an elemental conglomerate could serve as a way to show the true potential of many of these.

How could they look?

They could wear elegant, Archmage-like robes whose main color would determine what element was their base before they became masters (giving them more variation from just white, black or grey clothes), while also having some parts of them overflowing with multicolored energy.
