I did check the witch and light tags so im really sorry if you've already received this, but I would like to know about a witch of light. I hope you don't mind!

A Witch of Light could be pretty cool! With the relationship between Light and the Alpha, fate, wanting to change Fate, to change the Alpha Timeline, what should happen, could be an interesting plot point for a Witch of Light. In fact, it wouldn’t be too different from what Aranea tried to do. As a Sylph of Light, she tried to ‘heal’, improve a Doomed Timeline and make it more Alpha. A Witch of Light, instead, may nudge a non-Alpha Timeline to the path of Alpha-ness and try to un-doom it.

Other than that though, changing their Luck, their fortune, and their Knowledge, a Witch of Light could be very versatile in just about everything, not to say the literal interpretation of manipulating Light. Lasers anyone? I really like the idea of Light Players using Lasers. Sue me.
