Something very RPG Style with fights using either weapons or magic but also with some dark humor and a bit of romance.
In this kingdom, there are three races, humans, goblins and mages. Humans look like what you would expect. Goblins look similar to humans but are they have skin with a very faint blue, purple or green tint with faint scale patterns but they have magic that lets them alter their appearance entirely (they use this ability because most people are prejudiced against goblins and that it lets them walk without persecution). Mages look like regular people but their eye color changes with mood and they sometimes are born with unnatural hair colors like green or pink.
The rest of the details, someone else can try and make up like characters, kingdom names and the like.
