astrogate I'm thinking -> An excitable earthborn linguistics nerd who doesn't quite grasp sarcasm. Talks with her hands far more than someone with such respect for language and spoken word ought too. Never returns anything she borrows. She really wishes the dwarves spoke like they do in Tolkein, and may or may not have a running gag in her head that the dragon making everyone nervous actually has his own language that no one has figured out yet, and is just horribly misunderstood. [Insert Ace Ventura monster truck joke here]
Of course all of that nonsense is most likely a massive stress response to being shanghai'ed in a D&D game when she really wants to be back on Earth with a book and a big cup of Earl Grey, but who's judging?
