Yeah time is kinda screwed in the novels. I might just put a "Possibly" type 2 acausality for characters and mention the whole perceived reality shenanigans. Also, I think type 4 acausality is possible as well, since IIRC there are a bunch of worlds with different rules, such as Natural World (IE only beasts can exist here among other stuff), and how each category of a world is different from the other. Not to mention the whole "Cosmos" shtick.
Though I think the perceived reality stuff demonstrates the powers of Gravis more, since at the end of the whole, he fused both concepts of time and space to make Spacetime, a new concept different from Orthar's world. Since Objective reality only exists in one point, and if Gravis' can make an actual space-time (With infinite points) it demonstrates how the god tiers can just create whatever level of space-time they want. Might help a bit for tier 1, though this still assumes a few things, so I need to read Sword God in order to see if there are additional stuff that I can use.
Also, I'm reading Sword God from the beginning now and compiling feats in a blog, and I'm debating whether I should classify the whole Energy/Mana stuff as just Energy, or if I should mention Info type 2 somewhere (Still not sure if we can consider Energy type 2 by itself considering what Deon said).
