Retcons

Dimensional Retcon
Before the retcon, Kandalor was a planet separate from Marn which housed the Kandalorians. The Kandalorians were the fathers of the universe and watched over the other realms, including Marn. They sent Watchers to the planets to shape them in their image. This meant that Marn contained human life long before the Kandalorians showed up. There were many other realms that existed aside from the two, including a Monster realm and a world where Orcs were from. The Watchers were not divine, instead, they were other-wordly and could be seen as trespassing in Marn.

After the retcon, Kandalor and the other realms were erased. The existence of Kandalor was erased, and the title of Watcher was given to every previously established Kandalorian. Watchers are akin to Greek Gods and Titans instead of Aliens. The Mantle of Watcher was not given to individual or select few, every Watcher had the title but each was given an area they were in control of. Like a Watcher of the Sea.

Typhallos, Kenlow, and Elwood are the three of the last living Watchers. Unlike previous watchers, they do not have specialties and have divided responsibilities among themselves. Watchers have always been in charge of running Marn to vitalize human existence. And like Elwood, it was not uncommon for Watchers to be twisted to darkness.

The "Demon Lords" that William fought were once demons of hell in the Christain sense. However, in the retcon they become demons akin to greek demons. William would be a demigod, making him half-watcher. Elenai too, would be a demigod. Along with the retcon, including this instance, the heavens and hells were connected to Watchers. The Angels were reworked into the watchers chosen after death. As time went on, eight Archangels were chosen to lead the high heavens since the Watchers began to die off. Thus, Mathis was chosen by the Archangels to become an angel.
