Care to provide any differences? It could be information missing or missplaced.
I would get the ball rolling first.
In the LN,Overlord Volume 2 Chapter 1,Narberal Gamma used "Rabbit's Ears" magic and "Message" Albedo
However this was done in Volume 3 Chapter 3 of the anime adaptation ,Confusion and Understanding instead of Volume 2 Chapter 1,Two venturers.
This event should had happened way before taming Hamsuke and bear-hugging Clementine .
So anyone want to just state any differences with your keen insight?
Btw still pissed about Naberal Gamma's rabbit ears.
