My Ysoki Xenodruid mystic seems to be a source of these so far. I've been playing her as a rather stereotypical 'tree hugger' type who prefers diplomacy to fighting, even when it comes to a space goblin invasion, and has a stash of 'herbs' stored in her cheek pouches.
Got a good reaction from the group right at the start of the game when we were going over our roles on the ship and I announced I was the chef, with a specialty of 'steamed bulkhead fungus' that she had collected from the nooks and crannies of the old ship they were traveling on.
Second game, after the ship crashed on a hostile world and the world started going all glitchy (without her having gotten into her stash, mind you), found that it was all a Matrix-like simulation by some drow. Once the party had awoken, memories scrambled, she started going on about whether or not the party actually existed or if they were a new virtual life form come to the real world.
Think the funniest aspect of the last game, though, was the fact that she out-damaged not only the Solarian, but the mechanic AND his combat droid, all combined, due to horrendous rolls on their parts, and no less than two crits with her club against an orc's knees. Then during the boss fight against the drow woman in charge, she began babbling about 'love and peace' (to sum it up briefly) and later about the benefits of 'delicious natural bulkhead fungus', which caused no small amount of brain damage to the boss (it's how I described using the Mind Thrust spell).
Next game, assuming we meet more peaceful and talkative sentient beings, I'm thinking I'll be greeting them as an envoy of the 'Virtual', and am considering trying to start a cult. *shrug* Hey, it's an option.
