[member="Cameron Sinclair"] There is precedent on Chaos, where people have made submissions of Canon items or planets to on any new events that occurred to them outside of canon.
I say go for it, post it with reasonable abilities/limits, and just mention at the bottom that it is an elaboration of that particular metal.
I highly recommend you keep it simple, as if you claim that it can block lightsabers, cut through beskar, and blow up the death star, I guarantee you people are going to look at you funny and insta-deny any proposal you set forth which includes the above. If it could do all that, don't you think it would've been more important in canon?
What ideas you got for it anyway?
