Some topics of discussion to start with:
Should Major Demons (2nd Archstone tier, such as The Old Hero, Maneaters, etc.) be scaled to the Giants of the Northern Land, since
this blog states that the demons that infested the Northern Land capped out at this level?
The Old One/Bad Ending Slayer of Demons upscaling from The Monumentals (basically, finding out how many Monumentals are/were in The Nexus, thus determining how many were needed to reliably keep The Old One restrained)
Monumentals TK lifting strength (based on this art of The Nexus) (also means adding TK to Slayer of Demons end-game keys, or at least their Good Ending key)
Changing Good Ending Slayer of Demons to "at least Low 5-B", on account of them becoming the most powerful Monumental
Determining whether the Slayer of Demons' speed improves as they get stronger/whether Supersonic is just the cap outright to the verse's speed.
General verse cleanup
