Gallarth saved himself

Galarth is a powerful paladin and the highest-rank adventurer of his guild who has taken missions of all types and dificulties and defeated all kinds of villians and monsters, but the one that he despises the most are goblins, lowly, gross and weak monsters that don't exist for nothing but for stealing, and killing others, they were an awful vermin that should be exterminated from the world, but unfortunately they were as hard to get rid off as cockroaches, for each one that was eliminated, 3 more took their place, they had an insanely high breeding rate, they left bunnies to shame. This hatred made it all the most humiliating, painful and ironic when Galarth woke up one night and find out that he had turned into a female goblin for unknown reasons, what will he do know, and what will be done to him, or rather her now.
