It's an Ionian crystal which bears some resemblance to rudimentary perovskite, which is, as you should know, a crystal with unique photovoltaic properties— Photovoltaic? It means "regarding the conversion of light into electricity." No, no, the gun doesn't create electricity; the gun induces an external combustion reaction. It's perovskite that— I just explained the perovskite! If you'd stop interrupting— Wait. I remember you. You're one of Cayde's Hunters! Get out of here! Shoo! The Cryptarchy wants nothing to do with you!
