Hi there, I'm kinda now here, so this might be something disscused before (although when I searched for it here I've found nothing).
What is the spoken language is Erfworld? It's English in the comic, but this might be just for our convinience. I believe it is English, only Erfworlders probably call it "Engwish".
You're not your character class.
You're not how much GP you have in the bank.
You're not the airship you fly.
You're not the contents of your item list.
You're not you fuggin' armor.
You are the all-fighting, all-spellcasting heroes of the world.
