The Lizard Man Heroes Arc
After Cocytus's failure in annihilating the Lizardmen Alliance of the Great Lake, Ainz decided, through the convincing of Cocytus and Demiurge, to change his plan from destruction to occupation. Thus, he called forth Nazarick Master Guarders alongside three thousand Nazarick Old Guarders and Nazarick Elder Guarders as a show of superior military force to the Lizardmen Alliance.
