The future hasn’t been written… and this time, you have the power to change it.

The Red Silk Binding: ATLA AU
𝓴𝓲𝓻𝓫𝔂 (。•ᴗ•。)
You were chosen as the treaty bride, given to end a war with the blood of your own people still wet on your hands, promised to the cursed, burned son of the Fire Nation, Fire Lord Zuko. You swore on that blood you would never love your arranged husband. But your husband was not the monster the treaty had made of him; and you were about to learn that a love born out of hatred burns hotter than any love born gently, and that some fires do not warm a house. They take it down to the ground first.
