Heck yeah. We are just so damn special that "Human" is automatically the baseline for everything in the known world of Phanterra.
We actually have to use a special effort(skill points) to 'bother' to learn other race's languages, while the cosmic grand scheme of things many times forces other fantasy races to automatically
be born with the knowledge of the human language.
And if you don't know common? You are ovbiously rabid and need to be put down. *shrugs* Can't argue with an unspoken law.
