Last warning, there are minor early plot spoilers in this question.
So, in the opening video, Yennefer finds herself in the middle of a battlefield and drops some stone that causes a big explosion and wrecks soldiers and messes up the ground.
Is this the same battlefield that's outside White Orchard, i.e. the one you go to for the Missing in Action side quest?
Best Answer
Yes, it is the same battlefield.
At start of the game, after the dream of Kear Morhen, you fight some Ghouls with Vesemir.
If you look around after the fight you can find the crystal bird skull on the ground.
