Emrakul Brood - Brisela 1

The monstrous angel's two heads uttered a discordant wail that stabbed her ears and upended her equilibrium, and she had to clutch the pommel of her saddle to keep her seat. Below her, twisted monsters surged forward as uncorrupted humans clutched their ears or staggered back under a renewed assault. The angel-thing swept one of its thick lower tentacles through the throng in the square, sending humans and horrors alike scattering or crushing them to the ground.

If anyone was going to face this nightmare, Thalia realized, it had to be her. Her gryff's wings made it possible, which was more than anyone on the ground could say. She steadied herself in the saddle, adjusted her grip on her sword, and rose to the angel's eye level, above the broken roof of the cathedral.

Despite the creature's enormous size, its heads were no larger than Thalia's own, and some hint of their angelic features remained, including a tangled mat of reddish hair.
