A render of hikarito, and a pair of wedding bands. Yes those wedding bands are Mobius Rings. No, that is not a Kyber crystal. It's a small Zero Point generator. Kyber crystals don't exist. Neither does Disney Canon for that matter. This project isn't from that franchise, anyway; especially since energy swords predate StarWars by about 30-40 years. =)
There were no new StarWars films, anyway; those were simply the worst Star Crack films ever made, and it was all part of a Sith plot by Darth Mickey.
