I ' m not defending the Tories economic policy . I ' m pointing out that judging the Tories ' economic policy using the deficit 4 years before they took power as a starting point makes literally no sense at all . <| sep |> I think we discussed this before . We thought either Taken eventually fade away , or they lose their form , so Oryx needs to keep taking to replenish his army . The other thing we thought was maybe the Taken have a location they can be called from , for example putting a Taken vandal from Venus onto earth isn ' t a problem , but putting that same Taken vandal to a world a million light years away would not be possible . This is all pure speculation of course , there ' s never been a proper lore reason as to why we do not see other races .
