Dark Watchers and the Tablet of Mount Hermon

Examples of Evidence of the presence of Dark Watchers on Earth maybe few and far in between but the examples are quite compelling. From the discovery of giant humanoid bones to the secrets hidden by the Smithsonian, the Vatican, and Mystery Babylon cults who are more than capable of hiding such evidence. It leaves a lot of room for further discovery and it validates the questioning of the narrative we have given. But where are the Dark Watchers today? Have they left any evidence behind that we don't know about? And who was Sir Charles Warren? Why did they hide his discovery pertaining to the Dark Watchers on Mount Hermon?
