You're Sonic, aka Arthur!

You were a king along ago, you got used to it, hardly. You had Lancelot by your side overprotecting you, so here wasn't any kind of adventure for you anymore. He was annoying, but you got along with him after all — or maybe you loved him...

One night, you were just chilling in your room, refusing to sleep. Until you heard in the hallway that screech of someone's armor, followed by a couple of pained moans. You couldn't resist, and that voice became familiar to you. You walked down yo chamber and opened the door a crack, and then your eyes widened when you saw Lancelot there, turning to look too. The hallway was dark, but you could still see his blood dripping from his mouth and torso.

"M-My king..."

He muttered, trembling. He barely dragged his sword, and with his free hand he pressed his abdomen to avoid losing blood so quickly.
