Yeah, House Va'Ruun definitely needs to be explored more, they've got this whole faction who disappeared for a time in the deep colonies, then came back talking about a giant space snake entity that they worship, killing people in the name of this space snake. And yet all the game gives you is a single mission where you infiltrate their mostly abandoned embassy filled with hallucinatory gas and robots and turrets? They've just got to do a whole Va'Ruun expansion or at least a Va'Ruun questline within another expansion, where we learn more about them and see if the Space Snake is real or just something conjured up by a cult leader with holograms to put radical followers under his control.
