Tempest decided to travel through Equestria instead of accepting Twilight's offer to stay in Ponyville, to help other ponies, when she was in Canterlot she met Star by accident.
Star Tracker is a resident in Canterlot. Star works in a magic library as an assistant in the astronomy department, star tracker from a colt, he was a very good as a star reader, he was always interested in stars and constellations, he has many books in his house about constellations.
He was in a hurry for his work, and then he ran into the most beautiful mare he has ever seen (he said that to tempest XD really smooth tho)
Tempest was really surprised by this, she never really had that kind of praise (she thinks she scares other ponies a little, no male has treated her like a 'mare' because how she treat others, when she was a filly she had a crush in a colt, he rejected her and even began to bully her until she faced him,then a very bad situation happened).
Star was really shy and uncomfortable with the mares (this because as a foal, everyone made fun of him), but for some reason he was really … calm and not afraid of her, he wanted to know her more….. They started to know each other until they became a thing. Tempest at first wasn't sure of having anyhing with this…weird dude, but then she started to feel something for him, he was indeed a really good friend, they had a lot in common, she felt normal and loved by him, he loved her as how she is,he didn't wanted to change anything about her….she was perfect.
Tempest started to change a little bit, she wasn't as cold as before with ponies, she started to be really friendly with others. She is married and has 5 uWU children, Star always liked the idea of having a large family, he is a unique son with no siblings, so … he liked the idea of having small fluffy balls running around the house.
Tempest always recieves a LOT of kisses from her husband, but first in her scar and broken horn. the first time he did this she was blushing a lot, she didn't know what to do!!! but it felt nice, really nice… They both train together, Tempest decided to work as a guard but Star didn't like the idea of this..they had a family, he didn't wanted to lose her… They had a fight because of this, they solved everything, and tempest promised him that she would work for a while and then leave.
They live in Canterlot, in a big house full of books and stars (they live in a house where the walls have drawings of stars and constellations)
That's all i guess…i will keep adding information to this later :D!
