It seems to me rather the opposite: that Shar is the enemy of the absolute. My guess
It's Shar who tampered with the tadpole using shadow magic and this magic is what shields your character from the absolute's powers. Which is why the goblin priestess, once she sees "the shadows" in your mind when you talk to her, tries to kill you. The absolute cannot access your mind directly; it can only "see you" through the goblin (since it seems to have a direct mind link to its followers) and gives the order to kill you once they notice the netherese magic on the tadpole. Which also implies that everytime you use the tadpole powers you weaken the shadow magic protecting your mind, and that is why the absolute can now invade your dreams.
Nice! And that would explain why she hasn't hindered up until now. Can't wait to see which theory is correct . . .
Interesting theory. It would explain the magic phenomenon saving you right before you hit the ground on the beach and the fact Shadowheart always tries to get to you compared to the other companions who seem to be lost forever if you don't recruit them the first time.
