It's fine if there isn't. I'm just new to the game and wondering if this function exists. Because I named my characters something dumb. It's my own fault, of course!
I think you can do this at your home castle. When you go there, I think there is an edit button next to your character name. I can't remember the thread I read this in, but I remember seeing it earlier in the week.
Yep, there's a little pen/pencil icon next to the character name when you're at your keep. Click it and rename as you wish.
