[@CrystalApple] I'm not sure how cool I am with your bard's instrument being an organ. :/ Something so large would not be able to be summoned easily; would you consider starting with a smaller portative organ? Plus, an organ wouldn't necessarily be unheard of (except for countryfolk [s]but what do those potato sacks know?[/s]). Not that they wouldn't be rare, they definitely would and you character would find those who were unfamiliar with it.  

Also, I would need an explanation as to how your character would get such an instrument because it's an item/tool/weapon. That instrument would be an Asset because it is not normal (can be summoned) and the implied fact that it unknown.
