[@Zeroth] I'll gladly take any lore you want to give me on his family, though I may not be able to work it into stuff right away.

Also, you don't specifically need to mention the debut spar, but the opening post is mostly just sorta to set up your character's state of mind and how they've been faring going into joining the knights, so the debut spar might be important to that? IDK. Basically, just establish your character however you like~.
