This traffic sign on Corellia made me wonder. What would it mean? "Beware the aliens?" You would hope the whole Taris thing was buried well under the ground by now*, but I could imagine my twi'lek Y-u'no being perplexed as she halted her tauntaun to look at the sign.
On second thought, the aliens don't resemble twi'lek at all. They are more of the E.T.-phone-home type, but then the mobile version. They also look more like the archetype of evil aliens (think: Alien vs Predator) that we are to believe want to invade Earth. Or maybe I'm looking at this for too long and it just means: "watch out for people crossing the street" (with some imagination the figures represent a daddy alien with two children).
Either way, Y-u'no moved on, in search of more datacrons.
* Before the devastating bombardment, Taris was racially divided in different levels with humans living in the luxury top apartments and aliens in the cheap lower grounds. Play Knights of the Old Republic to find out more (and if you haven't played it yet, this classic is absolutely worth it!).
