Is morg the with that is described in vaynes lore? Haha just curious does it in any way connect?

Not bloody likely. Morgana isn't a mindlessly sadistic card-carrying villain. She's permanently angry and has given in to the dark side for the power to oppose Kayle, but she doesn't go around doing bloody murder for sh*ts and giggles.

i(along with a few other people) believe that the witch was leblanc in disguise

:-O or is it the same witch that cursed trundles tribe? Or is that a guy. Im not sure hmmm gotta look at it again. It be cool if its the same though and it becomes a new champ
