Perched atop the aviary was a magnificent raven. And it was talking, or at least that’s how it seemed. “I am the Herald of Thanatos, bringer of death to the world. Hear me,” it croaked. Below it, in the cage, the seven ringed ravens of the Tower bobbed and ducked their heads, gronking and cawing as the raven spoke. The crowd seemed delighted, laughing and filming the bird.
