" I’ll make one more promise,” she said, folding her bloodied hand into a fist as she lowered it before them. Darrow tensed.
Her blood dripped onto the sacred soil of Terrasen, and her smile turned lethal. Even Aedion held his breath beside her.
Aelin said, “I promise you that no matter how far I go, no matter the cost, when you call for my aid, I will come. I promise you on my blood, on my family’s name, that I will not turn my back on Terrasen as you have turned your back on me. I promise you, Darrow, that when the day comes and you crawl for my help, I will put my kingdom before my pride and not kill you for this. I think the true punishment will be seeing me on the throne for the rest of your miserable life. "

― Sarah J. Maas , Empire of Storms (Throne of Glass, #5)
