A continuation of this post. A few of these headcanons are based off this short fic I read. 

* Cor makes the tabloids when he at the young age of 15 is appointed as King Mors’ body guard. Mors took great interest in the boy’s growth over the past two years and had Clairius keep a watch. Neither man could deny the genius the boy displayed when it came to being a crownsguard. 

* Cor would have been happier except He knew that this promotion of sorts would only bring more controversy to the Lucian affairs. Politicians and civilians alike would criticize the decision to put a 15 year old in such a position as an obviously rash move to mock other countries. Cor as the king’s bodyguard was almost a taunt, that the Lucian children were even capable of taking down threats. His entire presence in the Citadel was often topic of controversy.

* Cor doesn’t have any friends when he’s younger in the Crownsguard due to being under pressure of doing his best so he can prove his position. It’s hard to find others who support him.

* He gets along with one of the older Citadel chefs who always sneaks him any snacks when she can. He’ll usually get off a mission and find a small box on top of his bunk bed with a note describing what it is. He enjoys the surprise and doesn’t admit that his heart swells whenever he sees her. 

* There’s an old man who tends to the palace garden on Sundays. When Cor has time, he likes to go to the garden and nap in one of his many hiding spots. The old man will talk to him and tell him stories about his life. He;s tried to ask Cor questions, but that teen only answers with short, polite phrases.

* He doesn’t want to get close to them because he’s afraid they’ll be next to die if he admits he likes them.

* Clairius takes him camping when he can get Clarus to fill in for the evening. Cor always somehow gets roped into some self imposed fiasco. Once Clairius saw a bat sleeping hanging upside down and he sighed, muttering “Couldn’t be me” and for some reason Cor’s spiteful ass took that as a challenge and was like “I CAN, WATCH ME” and spent the night in a tree trying to sleep upside down. Clairius didn’t say anything but he couldn’t sleep because he was worried that the boy might fall and split his head open. Neither got much sleep that night.

* Mors: I thought you went camping to destress. You look like you’ve aged 10 years.

* Clairius: “Do you want me to make YOU look like you’ve aged 10 years? ... Majesty.”  

*  Cor is often stoic when on duty (And when off too let’s be real) and no one really knows where he learned that or why he does it. (It’s the deep rooted trauma of various life events b but we won’t get into that rn)

* There is always someone talking behind his back. He’s too young. He’s too reckless. He’s too emotionless. He’s too vicious. He won’t be vicious enough when it counts. 

* He’s heard it all. It hurts, but he hardens his heart. He has a duty and he will fulfill it.

* He wears the military cap now. He’s at an awkward age where he can’t really predict what his limbs are going to do, but wearing the hat makes him feel less awkward. Not that anyone can tell. He’s always by King Mors’ side, crossing his arms behind his back and facing forward.

* Mors tries to make him laugh sometimes when he’s bored, but he’s yet to crack the boy’s exterior. 

* He’s never spoken to Prince Regis except for when he’s been sent to convey a message. There have been many occasions where he has overheard Regis dismiss him only to be rebutted against by Clarus. Cor won’t admit this either, but whenever Clarus puts Regis in his place, he feels a little happier.

* Sometimes Clairius invites Cor over for dinner. It’s just him and Clarus, so having another person present is always a pleasant time. Cor doesn’t really talk and instead prefers to listen to the father and son talk about their days. Clairius will sprinkle in a praise or two in Cor’s favor. Cor will usually wash the dishes, and has physically shoved Clarus out of the way so he can do so. 

* He thinks Regis is stuck up and wishes that he was a bit nicer to King Mors. Has almost started a fight with the Prince because he kept interrupting the king when he was speaking. 

* Mors senses the tension in Cor whenever Regis is present and has Cor go with Regis to Accordo in order to check up on the allied forces. Cor doesn’t question it, but Regis openly asks his father why he thinks he needs a kid dispatched with him. 

* Regis in his early 20s is lowkey a bitch but means well is all I have to say about his characterization. He’s understandably perplexed at the idea of having to rely on someone much younger than him for protection if push comes to shove.

* Cor isn’t afraid to speak his opinion whenever anyone on the team makes a bad call. This causes a lot of conflict with Regis who has to push down a childish urge to fight a 15 year old. 

* Cor is constantly on edge because he feels like Regis is trying to find a flaw in him so that the prince will have an excuse to let him go. Clarus just watches this all unfold in silence. He thinks the two need to figure out something on their own. 

* During their retreat from Accordo, Cor gets injured trying to protect Regis. He’s hospitalized and greatly upset about how the situation unfolded, calling Regis out on how he shouldn’t have retreated. 

* When he’s finally alone in the hospital room, Cor can’t help but start getting lost in his thoughts. He feels like such a failure. He couldn’t even protect that stuck up prince. The son of the king he’s supposed to protect. He doesn’t realize he’s gritting his teeth until he can’t breathe and once he gasps, the tears start flowing. 

* Clarus is the one who walks in on the scene. Being one for emotional openness, he urges the young boy to tell him what’s going on. Between the sobbing shut ups, leave me alones, and various incoherent swearing, Cor can’t get a handle on himself. It’s the first time he’s ever let himself cry, and honestly he has no idea how to process it. The more he remembers, the more failure he starts fixating on, the harder and more violent the sobs are. Clarus pulls him into a firm embrace, ignoring Cor’s attempts to freeing himself. Eventually he stops fighting and tries to calm down. 

* They don’t talk about it ever again, though Clarus does mention in passing that he’s always willing to listen. 

* Cor goes back to being Mors bodyguard until he’s suddenly shifted into the position of Regis’ bodyguard. 

* Being Regis’ bodyguard is exhausting for Cor mostly because Regis tries to befriend him. Cor is pretty hard to break for the next few years. He offers his witty comebacks and snaps on the daily, but he doesn’t really start bonding with Regis for a while.

* Regis is butthurt about this and does anything in his power to try to get the kid to crack a smile. Part of him regrets the actions he took towards Cor and the words he spoke, so it’s his way of showing that he’s sorry.

* Cor, like any normal teenager, feels smug about this.

* Clarus watches in disdain as usual. But looks the other way when the prince tries to rope him into some scheme. Sometimes he gives in though, just because seeing the faintest hint of a smile on the young crownsguard’s face is gratifying.
