Drudge

Drudge's, also known as Construct Undead or misnamed as Zombie's are undead created by necromancers or other beings capable of creating undead, such as vampires. These undead are the only known undead who rot and decay- to varying degrees and are often subservient to a master, though this isn't always the case.

Classifications
There are different types of the Drudge and they are truly the most diverse form of undead. From skeletal nightmares to nearly fully functioning people.
 * Zombies: The most common form of Drudge and Undead as a whole. These are created by necromancers and vampires in two different ways and act as a virus. When a zombie bites or scratches a living person, the person will then turn into a zombie, subservient to the original zombie's master.
