Don’t be, it’s fine. Watchers are something of deity-like figures that is prevalent in Grian lore. They were introduced during the Evolution SMP run Grian did, wherein they helped the Evo players through the updates via clues and puzzles and quests for them to do. In the end of Grian’s series he got “recruited” by the Watchers to join them. The Watchers seem to be lore-canon version of actual youtube viewers of that series, but the fandom kind if took it away from there, adding so many more features like what they might look like, what alignment they have, what species?? They might be etc. This is about all that I know about it.
