arthur somehow summons a genie (or smth similar) and is given three wishes with some restrictions: can't wish for more wishes, can't wish for love, and can't wish to bring anyone back from the dead. after some deliberation, arthur’s first wish is to be able to see the truth, to see people for who they really are. he has been lied to and betrayed enough times, he wishes to see clearly. the genie grants him his wish. he doesn’t know what else he should wish for so he pockets the other two. he returns to camelot and notices how different people seem. there isn’t anything physically different with them, they look the same to him - same clothes, same hair, same face, etc., etc., but there are some who walk past surrounded with gold. as they pass by arthur, he feels safe and protected and knows that they’d make a good, loyal knight. he walks past some that bow to him as he passes but are shadowed in sludge. it makes arthur nauseous as he passes. they are not to be trusted.
arthur continues and sees a woman and man run into one another outside a shop. they shoot back with apologies that stutter off when they meet each others gaze. a red string ties around their ring fingers, connecting the two. they continue to converse, helping one another with what they dropped, their fingers brushing and causing them to blush. he walks past two women who also have a red string connecting them, but a man shuffles down the street and wraps an arm around one of the women. he kisses her cheek and both women look away from one another. the man doesn’t have a string.
he runs into a few of his knights who prove themselves to be as loyal as arthur believed them to be. though there is something different about them, their…auras? energies? are more fractured. they shift as the seconds pass them by. gwaine has a constant dark blue that curls around his gold. when arthur focuses on it, it pulls at his heart, an ache in his soul, some sadness he doesn’t fully understand. lancelot’s is fuzzy and shifting faster than the others. he has secrets, many, but the gold remains true. he has a red string wrapped around his finger. arthur doesn’t have to wonder who it's tied to for long, as guinevere strides around the corner a moment later. hers is golden with loyalty, but the dark blue of sadness lingers and grows stronger when she notices lancelot and arthur are together.
it hurts but arthur cares deeply for both of them. her red string isn’t tied to his finger. he’d be the man in the street disrupting the two women’s conversations. a heartache borne through loyalty. arthur will let her go. she and lancelot will be happy. arthur will survive. this is what he wished for after all.
arthur returns to his chambers to try and work through his headache but the silence doesn’t last long before merlin is bursting through his door and striding across the room towards him going on and on with some lecture about how arthur should really stop sneaking out and at least tell merlin or leon where he’s going. merlin is surrounded by gold, stronger and more vibrant than any of his knights. his energy is even more fractured than them too, shifting with each word he speaks. its fuzzy in the way lancelot's was, a lot more fuzzy. a lot of secrets. there's a dark blue, a deep sadness, that arthur hadn't been aware of. merlin reaches up to pull a leaf from arthur's hair and the king watches as the sadness ebbs and a rich pink pours over it.
arthur's eye catches on the red string around his finger that leads down to arthur's own.
merlin sighs and fiddles with the cape over his shoulder, babbling on and on as he takes care of arthur. the blue fades into almost nothingness as the pink and gold meld further and further together with each touch. his energy is also...bubbly? sparkly? it feels more alive than leon's, gwaine's, lancelot's, and even gwen's do. he wasn't entirely sure what it meant.
until he saw the same with gaius's. and audrey's. and mordred's. until he saw the same on the young man brought to his knees before arthur and accused of sorcery. until he ran into a camp of druids and saw the same energy so full of life surrounding each one of them, the energy of magic.
