User blog comment:CrimsonWarden/Nazarick's NPC Level Count/@comment-26952857-20160916072620/@comment-29248623-20160917023317

Obstendro, I was thinking about the Demon Lords under demiurge but their numbers and levels are not specified.

Mkprovince, I actually came to a lot of trouble in tabulating the numbers if I included the mercenary NPCs because they would bust the level cap. Example would be the mention of Nigredo's room contain a horde of Carrion Babies that were just added there by Tabula Smaragdina for dramatic effect. Just from the statement given by Ainz there, I made the assumption that mercenary NPCs affect the data cap for an area of the guild and not the custom NPC level cap of the guild.
