Windburst (an avengers soulmate au)

What if on the day that you turn four, your parents get killed right in front of you? Well for Astra Sky, that's exactly what happened. Now, she has to run from these strange men who are chasing her. But, what happens when your soulmarks go haywire while you run? Now, she has to worry about not only being chased but also piecing together who her soulmates are. Yep, mates plural.When a child turns 10, their soulmark(s) as a tattoo on their body. Astra has 36 soulmates. The most soulmates ever recorded was 6. And it gets worse, everytime one of your soulmates gets hurt, a small crack appears on the soul mark. When a soulmate dies, their mark turns pure black. What will happen when she's involved in a massive war, and gets to meet the avengers. (In this au, no one has died and all of the avengers are soulmates and are already together. They are just looking for their last piece)
