Lissandra - Master Manipulator in Old Lore, Coward in New Lore
So in Lissandra's old lore, she was one of the 3 sisters. Except, instead of being a powerful being of authority to bring peace the Freljord, she secretly plotted with the enemy to bring them into the world, and place them on the throne, with her, ever loyal, at their side. They were the Watchers, she was their vassal, and she devoted herself and millennia of plans to erasing her misdeeds from history and to infiltrate the Frostguard tribe so that she would have her army to ride with once the Watchers were freed from the Abyss. Her entire being was devoted to her cunning manipulations as she sought a way to bring the Watchers back so that they would grant her power and a position alongside them in the world.
In her new lore, she's one of the 3 sisters. But when she loses her sight, she sees the Watchers in the dreams, and strikes a bargain with them for immortality. When they arrive she chickens out, and she sacrifices her sisters to the Watchers, and then betrays them, trapping them in true ice. Then she sets about planning to delay them for eternity? Her new lore deviates hard from her old lore, and paints Lissandra, who was formerly a back stabbing manipulator with all the cards in hand, as a coward who would throw her sisters in front of her to die so that she can live another day. Just no. This isn't Lissandra. Lissandra hides in the shadows because she's planning things. She doesn't hide out of cowardice and fear. Lissandra has basically become one of those "NEW WORLD ORDER" rednecks who has locked herself in a compound (the Frostguard village) and is hoarding guns and ammo (True Ice) to defend against the lizard people (Watchers) so that she and those around her will survive the inevitable armageddon that follows. This is a horrible way to paint Lissandra.
