Baba is the guard of Grotta, Chieftain of Syrus' estate. He keeps a constant watchful eye over the Hall of Judgement, and refuses Levant access regardless of when he is asked.
Apparently, he is somewhat envious of the sick after the Onibubu attack, as they are held in eternal slumber where he has to work. He also expresses interest in the legend of the Birdman, Kikinak - wanting to be able to fly as he does.
After refusing Levant entrance to the Hall of Judgement after Garai is taken, Baba is seen engaging in an argument with him before being blinded in the white light from Garai. Therefore, he is the very first person seen to be petrified.
