Trivia
In Overlord, the author seems to set tiers for vampires:

Lesser vampire: reanimates resurrected by vampire brides' vampire innate feat or summoned by spell-casters; a zombie that possessed minimum intellect.

Greater vampire: reanimates resurrected by Shalltear's vampire innate feat or summoned by powerful necromancer; typical vampire, more intellectual and powerful than lesser vampire.

Vampire bride: transformed by Shalltear's vampire special skill (or other high-tier vampires ?); an undead even more powerful than normal vampires (in WN, Brian receive power boost and spell-casting feat), but Shalltear can only have limited brides with her.

Vampire lord: title given to a powerful vampire (?), estimated lvl 60~70.

Origin Vampire: more like a monstrous undead with very little human quality, origin vampire create other lesser-tier vampires, in general it is impossible for lesser-tiers to become origin, even atavism has limited effect (as hybrid cannot become pure-bred).

True Vampire: above all and only exist in Yggdrasil. It is Shalltear race.
