I have the character in question all planned out, He's Dour, Cynical, and a Devout Paladin of.....I haven't decided the Deity yet, but his whole shtick is he's a good person disillusioned with his own kind as he sees their tendencies as Self-Destructive and wants no part of it, and upon saving a Cleric he finds a path. Unfortunately being a 'Goes into Goblin Slayer Abridged Voice' FILTHY GAAAAAAAAAWBLIN 'Exits Voice' everyone immediately assumes the worst of him and it's worn him down (Hence the Dour and Cynical part.) but at the end of the day people treating him poorly doesn't stop him from doing the right thing, even if it means the people he tries to help try to kill him afterwards.
So everyone hating him and/or Mistrusting him for being a Goblin is core to this character.
Also being a Paladin devoted to a Deity, but given how Paladins been added in the game so far I might have to do some retooling of the Character.
