The Magic of Game of Thrones

Game of Thrones is officially diving deep into the world of magic!  In the beginning this was a political strategy show and now it might be turning into something along the lines of dragons verses ice zombies? (A phrase coined by other GoT fans, not myself.)

Here are some questions I have about the logic behind the magic of the lands of Westeros and beyond. Please comment below with your thoughts and theories!

Bravos / Arya Stark:

What does it look like when the faceless men change faces since the actual shot is never shown?

Why do the faceless men also kill good people?

If the faceless men have access to any face from the hall of faces or if they have to physically take a face from the hall every time like Arya did in season 5 episode 10?

Beyond the Wall / The Children of the Forest 

Why does stabbing a man with dragon glass turn him into a white walker?

If a man is stabbed by dragon glass by another man, will he turn into a white walker?

Why do the white walkers continue to use patterns originally used by the Children of the forrest (i.e. the stones arranged by the children of the forest in season 6 episode 5 is the same as the arrangement of horse heads left by the white walkers in season 3 episode 3)

Beyond the Wall / White Walkers

Why does dragon glass kill white walkers when it originally created them

Are the white walkers fingernails made of dragon glass and is this how the Knight's King (leader of the white walkers) turns Craster's bastards into white walkers?

Meereen / The New Fire Priestess 

Is the lord of light blood magic?

Is the lord of light a lord or an ancient magic put into practice?

Has the new fire priestess seen Daeny in the flames just like the Red Woman has seen Jon Snow?

Is there a possibility that Jon and Daeny will both end up fighting for the iron throne? (And are they related!? WHEN will we find that out!?)

Which servants of the Lord of Light have the ability to bring people back from the dead and why?

Beyond the Wall / Bran

Why can the white walkers see Bran when he is in his visions?

Why can the white walkers touch Bran when he is in his visions?

Why does touching Bran allow the white walkers to penetrate the children of the forest's force fields? 

Why don't Bran and Hodor and Meera run the moment they can?

How can Bran leave if he is going to be the new three eyed raven? 

Does Bran need to be holding onto the tree to "download" the information? 

Can Bran connect to another weirwood tree?
