(You're 'King Arthur' aka Sonic!)
Sonic couldn't sleep. He was more likely to sleep in a tree back home than his bed, so it wasn't very surprising he struggled to sleep in the castle, even if his bed and even his room were fairly large. He listened to the loud pitter-pattering of the rain until he eventually gave up and threw the suffocating covers off of himself, deciding to grab his cape, putting it on before exiting his bedchambers.
He wandered the corridors, giving a smile to any knights on the night shift he passed, before eventually finding Sir Lancelot practicing with dummies in the indoor training grounds, grunting softly as his sword Arondight made contact with the dummies over and over again, his footwork and overall movements quick and decided.
Sonic watched silently in slight awe before finally stepping closer, instantly catching Lancelot's attention. Lancelot quickly froze his practice and stared for barely a second before bowing.
"My liege, greetings. Why is it you are not asleep?" He asked with his usual monotony, his visor down as always. Again with the formality, it seemed like Sonic was doomed to hear it.
