(you left your mark on me) a golden tattoo

Sokka woke up on his thirteenth birthday with a word tattooed on his hip in unfamiliar, red script. He knew immediately that he’d just gotten his soulmate. He also knew that his soulmate was not from the Water Tribe. He couldn’t help but panic, because the writing was in red, and red meant only one thing to the Water Tribe, and that was fire. His soulmate was from the Fire Nation.Sokka groaned and rolled over, pressing his face into his pillow and wishing that it could all be a dream.---Zuko woke up on his thirteenth birthday with gentle, blue writing curving over the left side of his rib cage. His soulmark. And his soulmate, whoever they were, was not from the Fire Nation. They were from the Water Tribe.His father was going to kill him.He always knew that his father would lead to his eventual demise, but he’d hoped that he might make it till sixteen, at least. Looks like he got thirteen years. He’d had a good run, but if his father ever found out about his soulmark, he’d have Zuko burned alive.
