Excerpt from the Creation Tomes
" And it was decided that there should be guardians made out of mortal men to protect their brothers and sisters.
And the Creator declared that there should be twenty and four of these guardians which He named Watchers. And they were deemed Watchers because of the blessing of divine sight which was bestowed upon them.
Behold, this blessing was given to each in the form of a wooden mask that when worn granted the Watcher divine sight. And these masks were made of a single tree, yea even one of the oldest trees remaining on the earth. And the craftsmanship of these masks were exceedingly fine although to the eyes of many they appeared plain and simple.
Now it should be known that the blessing of divine sight did work in many ways according to the righteousness of the wearer and the will of the Creator.
Yea, divine sight could even grant the Watcher precognition of events that had yet to come to pass. However it should be known also that divine sight could also be used to grant the Watcher improved vision in such ways that they could see men through barriers and walls, yea even the mightiest of walls constructed by man.
And it was also given by the Creator that the Watchers should use their blessing that they might see demons and wraiths and all manner of being which should not appear before the naked eye.
Yea this was done that the Watchers might protect those that these dark creatures would prey upon.
.....
And it came to pass that during the second age of man the Watchers were hunted by a sky-dweller named Ren-Thalgor.
And it came to pass that Ren-Thalgor, being a wicked and blasphemous man with delusions of godhood, did capture and slay many of the Watchers, yea he did even slay fifteen of the twenty and four Watchers.
And behold the masks of the fifteen were lost after their wearers were slain and it is believed that many of the masks were destroyed by those who did slay them.
But behold when times demanded it one of these masks would resurface into the hands of a righteous individual and this was done that man should not be destroyed nor led into captivity by those with dark hearts.
And behold, those with wicked hearts and intent would find no blessing of divine sight through the eyes of the masks.
Yea they would see the world as if they were without a mask. Meaning that the mask will only work when worn by a righteous man with a pure spirit and humble heart."
