His Constant

The line of black swelled steadily. Like a giant wave building and building before finally crashing upon the shoreline, they came. Morgana was easily seen at the head of the formation on a horse of pure white that so greatly contrasted with the darkness of her gown and now-familiar and now-annoying smirk. The sound of restless horses and the shing of swords being unsheathed resounded around them all.

Arthur's sapphire blue eyes narrowed at the oncoming army and noticed with a sinking heart that they were outnumbered. Greatly outnumbered.

"Here we go again."

That voice—it was a voice that resounded through his most treasured memories. It belonged to a man who was just as much a steady guide as he was a fool. A man who teased him as relentlessly as he protected him. He was a friend. A constant in his ever-changing life.

Merlin had always stood by him in his and Camelot's darkest moments—no matter the odds—and this time, though everything had changed, it was no different.

The King turned to his newly made Court Sorcerer, whose lips quirked upward and whose eyes danced with fondness and steadfast determination, briefly before looking behind him at the sea of scarlet.

Suddenly, he wasn't afraid.

For what was there to be afraid of? With non-magical and magical people standing on the same side for the first time since the Purge—with his men, his noble, inspiring, hard-working men—behind him, with his constant standing at his side…

He understood the eager sparkle in Merlin's eye, the exasperated humor in his tone.

He understood it very well…because there was nothing quite like the feeling of fighting side-by-side with your brothers.

And with a grin—a rather feral, mad grin—breaking through his stoic façade like the sun through storm clouds, Arthur agreed, "Here we go again."
