This is the first chapter of my trilogy which is called The Dragon's Kin'.

A few years after the mane six adventures Twilight returns from Canterlot and meets all her old friends. Not late after, she realizes that everypony she knows has a family except her.
So Twilight eventually takes a step to become a mother, but at what cost? And the fact that Luna is sick and Celestia is calling her back to Canterlot doesn't help... How will she manage? Find out eventually...
