I already semi made stories for them as well aha XD
The Christmas one lives deep in snowy mountains, keeping watch over the valleys below. The grey/white one lives in a dark forest, helping lost travelers find their way out. I know they tend to hide away from people, but I'm hoping the white one is an alright exception. She typically just guards the forest, but will use her flame/soul to redirect others. I guess it's more of how wisps work? Sorry, I'm getting carried away XD
