===Regarding how the Undead are different===

* Basically, undead are able to twist the normal rules. "Living" things have their soul contained within a physical body, but the nature of the connection means the soul cannot continue to exist in the body once the body degrades. Undead twist this logic, as for them there is no severing of the body and soul, for them the physical body is not a "vital" thing but rather an incidental part of the soul (which is now the main body) worn by the soul like a garment. Further, their physical body has "stopped," so there is no degradation. Carrying out life activities is what degrades a living body, but for undead those life activities are caused by magic and the soul itself manifesting those changes in the physical body, creating a "pseudo life" that mimics life processes while not deteriorating. It can also be said that because the soul is now the "main body" their body is pulled along by the soul's own immortality. (source: Personal communication with Kenkou Cross).
