I'd just have an alignment changer, maybe fred's neutral twin Ruth!
(looks the same as fred, looks must be shared in this family)
Hand in maybe some khyber dragonshards combined together (maybe 10 tiny shards?) and some coin to change your alignment.
Actually maybe khyber shards to become non-good, or more chaotic.
Maybe siberys shards to become more good and/or more lawful.
Paladin's cannot change their alignment.
Monks cant become non-lawful.
Barbarians/Bards cant become lawful.
