For Iden Nui I decided early on for it to have two kanohi of light, each with different powers of light. Here they are: Luceat and Lux Tenebris.
This is Luceat. It would have the power to emit light and control light’s speed.
This is Lux Tenebris. It would have the power to control light’s intensity and wavelength.
I hope you guys like them.
Update I made some colored versions.
One is older than the other, and should’ve been put up sooner, anyways here they are.
