Lissandra theory ¿

As we all know she is the most loyal servant of Frozen Watchers and now that we know that the Watchers are conquerors that take over worlds / planets . Lissandra having the gift of magic she is the ice witch and her goal became to unleash a new ice age over the whole world. Hmm. This could simply mean that she is just following the Watchers orders / motives but but but what if the magic that they give is actually like a mind controlling magic. They are granted powers but in the same time they aren't aware that they are under the mindset of the Watchers to do their bidding while they are away. Also LIssandra has the power to see the future that means that the Watchers had it too. So what if they give her that much power to continue doing what they were doing because they knew that they would lose the battle against the united tribes . Lissandra wants ice to take / conquer the world . The same idea that the Watchers had, to conquer. Or simply she follows what they told her to do. lol
