“You do not yield.
Aelin slammed her hand into the lid. Cairn paused. Aelin pounded her fist into the iron again. Again. You do not yield. Again. You do not yield. Again. Again. Until she was alive with it, until her blood was raining onto her face, washing away the tears, until every pound of her fist into the iron was a battle cry. You do not yield.
It rose in her, burning and roaring, and she gave herself wholly to it.
Over and over, she pounded against the lid. Over and over, that song of fire and darkness flared through her, out of her, into the world. You do not yield
And when she awoke chained on the altar, she beheld what she had done to the iron coffin. The top of the lid had been warped. A great hump now protruded, the metal stretched thin. As if it had come so very close to breaking entirely.”
― Sarah J. Maas, Kingdom of Ash
