• They start trying like four years post ACOSF
• And the years start to pass by and Cassian is like "That's alright Nes, children are really rare between the fae"
• Although he said that to cheer himself up as much as Nesta
• But when Elain gets pregnant after only one year and a half with Lucien, Nesta gets mad
• She's not mad at her sister. No. She's mad at herself, at her body.
• Nesta starts to think she's letting Cassian down. She believes she's a disappointment to him.
• Soon the feeling that she's unworthy of Cassian comes back, she's into depression again
• Cassian doesn't know what to do. He surely wants a baby, but above all he wants his mate to be happy
• Cassian tries to tell her that, but she just doesn't believe him
• Now Nesta thinks the only way to make her mate happy is to give him a baby, she even try to get a surrogacy
• When Cassian discovers that he gets possessed. But he's also really worried
• After that, Cassian calls Feyre and Elain for an intervention. For Nesta and himself.
• They both need to understand that they don't need a baby to be happy. So their new healing journey starts.
• It's been months since the intervention began, Nesta is almost over depression. They've past through this together.
• An year and a half since the intervention began and now they're happy with their mate's life again, they're happy being wonderful uncle and aunt to their nephews
• Four months later Cassian and Nesta go to Illyria trying to get down a bloody riot
• The village is destroyed, houses burned and a lot of bodies lying dead at the streets. Cassian and Nesta stay there to help the survivors and to appease the remaining rebels
• At the end of the day Nesta is walking through the house's wreckage and hear a little cry, she found two little girls under a piece of wood
• "Hi, I won't hurt you" Nesta said softly "Do you two wanna get out of here?" She asked the older girl who couldn't be older then eight by her appearance, the other one was a toddler
• The older girl nods quietly, Nesta carefully pulls the wood that covered them and throws it away. First she picked up the toddler, that was apparently not hurt.
• The older girl didn't move, tears in her eyes "My wings" she whispered. Her left wing was twisted at an awkward angle, a big cut in the center and bloodied all over.
• Nesta's heart stopped for a moment. She quickly helped the girl out of the wreckage and carried the injured Illyrian in her arms "Cassian! Cassian!" she screamed
• Soon Cassian was there and they took the girl to the improvised nursery
• Cassian didn't leave the little girl's side until her wing were properly taken care of and bandaged.
• Nesta stayed there too, the toddler in her lap.
• They soon discover that the girl's both parents died in the riot.
• They stared at each other for several moments, no words spoken, but it was probably the most important conversation they've had in their entire lifes
• From that moments their life would change forever.
• Family. That single word flickered through the bond. They've found family.

I obviously imagine Azriel with skin darker than those, but AI wasn't collaborating
