If there is going to be a dragon lord in the next volume, there is a chance that instead of CDL showing up it could be DDDL (Deep Darkness Dragon Lord). It was said that this dragon lord is living in a large subterranean cave and I assume the dwarves would have lots mines going through large caves and would eventually find one that's large enough to hold a dragon.

Plus, if the author had Ainz recuit DDDL instead of CDL, then the Theocracy could mind control CDL and we could get some DL vs DL action later.
