Sooo the monster thingy in Ryze cinematic....

That being that ryze fought....Has some similarities to the Frozen Watchers but is doesn't match their look. Maybe they changed their look maybe... But that thingy lost a battle against a rune mage...And that thing enslaved a whole nation....That thing was way to weak for a watcher..But there is a chance since the place was frozen and icy... But there is a chance that this could have been one of the troops of the watchers. Since we are told that a horde of monsters enslaved Frejlord not one or two..So as All of the watchers were pushed off the bridge including the Masters lords what ever you call them. That thingy is probably a troop. You opinions.... Mine I have need oxygen I lost mine while watching the cinematic
