User blog comment:Zack Tan/Ainz's Possible Future Plans/@comment-121.7.125.105-20151020164911

Now that Momon is helping to "rule" E-Rantel in place of Ainz, the need to keep the real identity of Momon = Ainz is really important. If the greater world learns of the truth, the fallout could be quite epic especially among the adamantite adventurerers eg Evileye.

For now there's at least 2 person outside of the guild that knows the truth.

1. Nifrea

2. Clementine

Since Nifrea is 'safely protected' inside Carne Village under the eye of Lupusregina, I think the information is safe with him. The problem is the body of Clementine and whether it was the Slane Theocracy (Windflower Scripture) who got it or some other unknown forces. If the Slane Theocracy got the information, it could explain why they chose to remain neutral when Ainz + Empire declared war on the Kingdom since they know Ainz is a very powerful magic caster.
