User blog comment:Nomad27/Predictions of what will Occur in Volume 10./@comment-26270724-20150910210821

At least one chapter will probably be dedicated to the reaction of PDL, the Slane Theocracy, and other major players that will soon enter the story to Nazarak's apearance. Since Momon was declared to be the enforcer of E-Rantel for Nazarak I can't see him being able to leave the city very easily or for a long time, if he does it will probably be under the pretense of being ordered to by Nazarak. There are two ways I can see Volume 10 developing as a whole:

1) Volume 10 will be more like Volume 4 and focus more on the action of the NPCs and the residence of the New World's reaction to them than on Ainz himself. Here's how I think the floor guardians might be deployed in Volume 10:

Cocyutus is in charge of the Lizardmen so he might be sent with the a combined army of Lizardmen and Undead to subjugate the demihuman army attacking the Dragonic Kingdom to test the Lizardmen's loyalty and gain powerful demihuman corpses for creating stronger undead while presenting a favorable image of Nazarak to the surounding nations.

Aura and Mare are in charge of guarding the open area between Nazarak and E-Rantel so they will probably be held in reserve.

Victem will definitaly stay inside Nazarak to protect it.

Pandora's Actor and Albedo will probably stay in E-Rantel to act as the faces of Nazarak and manage everything.

Sebas, covertly since he already has the cover of working for a wealthy noble, or Demiurge, as a direct representative of Nazarak, will most likely go to the Dwarf Kingdom to negotiate a trade deal.

Shalltear will definitaly need to be kept away from E-Rantel and doesn't already posses a cover story or exceptional negotiation skills. So, she will probably stay in Nazarak to defend it since most of the other Lv 100 NPCs will be out.

2) Volume 10 will focus on the struggles Ainz faces to keep the peace in E-Rantel and deflect Brain's investigation into the truth about Shalltear. I doubt that Ainz secret will be exposed so soon after Nazarak moved into the open so Ainz will probably find a way to deflect Brain's suspisions. Blue Rose will probably move to E-Rantel at Renner's request to keep an eye on Nazarak and because Evileye wants to be close to Momon. Due to Brain's investigation and Evileye's knowledge of the fight with Jaldabaoth Ainz will probably be forced to pull Evileye into Nazarak's fold to keep her from making the connection between Jaldabaoth and the masked maids to Demiurge and the battle maids resulting in Evileye joining Darkness.
