Tales from the Outer Rim
Hnn-rowr yrroonn nng rarrr!
Languages are not covered in the book, so I’m making the following house rule: you can usually understand other aliens as long as they a commonly encountered race (it’s assumed you’re just familiar enough with their language if they are not speaking basic). Aliens not commonly found in galactic society might require skill checks to communicate with. Conversely, allies and party members are always able to understand you, no matter how you are howling/beeping/lekkuing. Other members of the galaxy are a completely different matter.
