As much as I like the four armed freaks, they'll die out first. They're too separate from each other. Maybe if they unite with each other like they did at the battle of Twilight Gap, they might be the fiercest alien race in the solar system. Maybe they would have been as big as a threat as the Taken. But looks like Variks is going to be the last living Eliksni (butchered I think) in the universe for that reason.
