Undead

Undead (アンデッド) are creatures that have come back to the land of the living after dying and are found both in YGGDRASIL and the New World.

Background
Undead were look upon as monsters that possessed an undying hatred for all living creatures. The undead are considered to be the enemy of all living beings.

Yet there are few exceptions to this idea in which players like Ainz, an undead who doesn't see it the same way they do, but was still indifferent to them nonetheless in terms of not being able to show emotions physically.

Unlike the dragons' own growth rate, high-level undead is not the type to grow in bodily might. Instead however, they could accumulate knowledge and experience consistently over time. From that point of view, the undead might be even stronger than dragons.

In the new world, it seems there are legendary tales recorded and pass down about the undead. This being the Soul Eaters, which devoured the souls of the living. While another case being the Wriggle Pestilences, which spread disease. Additionally, Mage cabals which gathered many undead around a core of Elder Liches. For instant, Guphandera=Argoros, the undead dragon that lurked in a mountain of the dead and used psychic-type magic. Not only that, but Astral Rippers, masses of shadows which stalked the Valley of Shadows, and so on.
