[Game of Thrones] Which gods do you think are real?
gpt
None are probably real in terms of being 100% the way they're described. But the Old Gods and the Lord of Light are probably real in some capacity. 

The North definitely has some magic that could be derived from the Old Gods, warging and Bran's tree-boy stuff is real. So there is something magical connecting all of that stuff. Whether they're a set of animist gods that the old Northerners worshipped or something else is unclear.

The Lord of Light is implicated in some of the most replicable magic. The fire stuff is definitely real and characters are for sure brought back from the dead and have visions of the future. Whether it's some actual duotheistic religion with a fire god and ice god representing good and evil is not clear, but there is some actual magic going on.
