Ok so I like to think of The Watchers as really ancient deity's that just have been forgotten about by the years ya know? Like those old religious beliefs, traditions, history like ancient Rome, some legends etc. Because they are quite literally there from probably the beginning of the servers, and they are technically just a myth to most, so it's logical that people would stop telling the younger generations their story, bit by bit, they'd be forgotten about.
And by that logic, I think that no one, not even Xisuma would recognize a Watcher
So Grian could quite literally transform right in front of them, wip out his big ass 5 meter long, each, purple wings, have millions of very eery glowing eyeballs around him and be adored in the most prestigious, over-the-top, silky purple gowns and no one would suspect anything.
Or at least anything Watcher related, because there's probably would be theories of him being an alien or a shapeshifter...
Which is another headcanon of mine:
Grain is a shapeshifter!
Except, he wasn't always one.
At first he was a human, was born a human and stayed human up until high school and a little after.
It was on Evo when that changed.
I like to think that when The Watchers kidnapped took him with them, the transformation of going from a human to a Watcher doesn't just consider of having additional powers and wings that The Watchers have, because I like to think that they aren't just angel-look-alikes. They are eternal beings from over the world, and they technically don't have any shape at all. They can change into any shape or form they want to. That's just how they are. They are translucent, they can be anything and nothing at all. They are always somewhere and nowhere.
Because they see everything but no one sees them.
They are watching.
They see everything
They are everywhere
They are everything
They know everything
You can't escape them
You can't
You won't
You shouldn't
.
. .
. . .
They know
Xuelqa
Why did you run away?
You know you can't escape us
You can't go back to being a player and you know it
. . .
Well then... If that's how you want to be
You may go down
Go on, play pretend with the rest of those silly little creatures...
But you know you'll never be one if them ever again
We'll make sure you can't forget that
...there
Maybe if you can't see through the player's eyes anymore, you'll start taking things from a Watcher's perspective
Oh yeah.... They also took away his player eyes... That's how he's left with those two black holes in his face...
