Nik's meteor shower elemental came to her as she started longing more and more for the sky. her meteorite nature feature seemed to her at least to tell her that even if she was bound to the earth, she hadn't come from it, not like this, not entirely - and when catching a spectacular meteor shower one night something clicked for her emotionally. perhaps meteorites burn up as they hit the earth but they do so so spectacularly and so defiantly, literally ending in blazes of glory. she could reverse that. she could become ablaze on her way back up instead.
it wasn't that it was easy to learn to harness the elemental, but it seemed to come to her naturally, and she always felt that she was on the right path with it; a path that was long and winding but offered no resistance to her.
now she carries it with her constantly as part of her identity and a reminder to stay true to herself. in a more passive display it causes her meteorites to smolder and glow with a fire that isn't quite yet burning, but in the active display they are truly on fire, trailing flames where she goes, alongside her similarly burning tail.
