Type XIII

Type XII will happen when God takes control again and "resets" the entire universe. I suspect that He will erase our memory of controlling Him and we go back to Type X, so I conclude that Type XII refers to the constant loop between a Type X civilization and a Type XI civilization (if we even reach both types). But, maybe we can find a way to co-exist, or live with God in person (or being ;). He can help us advance from Type XII to Type 99.9 (says so in https://kardashev.fandom.com/wiki/Type_X that "civilization gets transported to a verse that goes from type 10.1 to 99.9"). I'll explain possible outcomes in Types XIV through XCIX in another article
