Just some thoughts on the taken king and acouple of other stuff

So Oryx has created an army of taken which consists of fallen, hive, vex and cabal that have been taken but at the start of ttk he's only at saturn and all the fallen houses that remain are on earth, moon, venus and in the reef. So how does Oryx have an army full of taken fallen? I think that that means there are or atleast were many more fallen that didn't chase after the traveller with others but stayed behind or went elsewhere to start again on another planet where they were then taken. So unless Oryx has already taken them all, there are many more fallen houses or just one big house thats been building up forces and waiting for their time to take back the traveller may be their in contact with the kings and are waiting for them give the signal to rush in unite the houses and take back what they think is theirs. Also another thing i noticed that isn't really lore related but i thought I'd mention anyway is that in the 'We are guardians' trailer Oryx thrusts his great big sword into this glowing plate thing which emits a big wave of greenn hive energy stuff which looks like an emp that disables ships in big space battle. I was thinking this may also be a part of the boss battle at the end of raid. Since supers seem to be pretty important I was thinking in the raid Oryx uses his sword to disable our supers and abilities or something along those lines. Anyway I thought this may be worth sharing so please say what you think about it and i hope it was atleast a little bit interesting.
