Since volume 11 and 12 will be about the Dwarf Kingdom and the Dragonic Kingdom, I bet they are the next ones to ally themselves to Nazarick. The most probably scenario is Nazarick helping the Dragonic Kingdom with the Beastmen Nation, so they gain an ally while they also gain a lot of strong bodies to use in experiments to create undeads.
