become the Arena champion is the inspiration.
some NPCs who acknowledge our achievement of becoming the highest champion will call us with "Invictus" or "The Invictus" to replace our name in the dialogues, not all, but only some NPCs who knows or regular viewers of Arena to make it more sensible.
it would be nice if we also have nicknames for respective settlements, for example :
some Hathorians will replace our name with "Kingslayer" after we helped them kill the Rathound King.
Geezer Ford will call us "Kingfisher" after he admitted that we are the better fisherman than him.
some Foundry people will call us "Beastslayer" after we killed the Beast.
and so on.
