Good evening . With the Nergal table you could change the appearance of your character (for their name and gender, I’m not sure). if you are on PC in solo/co-op there may be mods for that.
Like our friend @jmk1999 specify it, if you recreate a new character, all the possessions of the old character no longer have owners.
It’s up to you to decide if you all want to start again.
