Teferi's Response to the Terror of Aku

Teferi and Jabari travel over to Aku, which is said to be fraught with danger we don't actually see. They enter a chamber that was ancient and legends whispered of dark origins. Within this giant dome hung a huge imposing pendulum by a chain from the ceiling. It was usually a warning system to keep people out of this place,. but now it had fallen to the floor, the chain snapped, and it crushed someone beneath it.
