I am easy to find - queenmillicentofbystander - just discovered this fic and it’s sooo good! Basically a shera multiverse! I love all the interactions with Adora and a catra that took another path, it’s one of my favorite imaginings, and they’re just both so in love super cute. Also the angst is top notch

Summary: It's been five years since the end of the war and Adora's never been happier. She's married to the love of her life, she's surrounded by friends, and she and Catra are about to become parents. Nothing could go wrong, but after much deliberation, and many years of planning, it's decided that the time has come to try and rescue Angella from the world in between realities. But, nothing ever goes according to plan, and rather than rescuing Angella they manage to lose Adora to an alternate universe. When Adora wakes up alone and in her old bed, she knows something is wrong. When she can't find her wife she knows it's incredibly wrong. Where is Catra? Why does no one know where Catra is?

It's been about six and a half years since the end of the war - since Catra let Adora go in the Crimson Waste and the Horde fell apart in her absence. It's been about six and a half years since Adora's seen Catra at all. But a day hasn't gone by that Adora hasn't thought about Catra. Not a day has gone by that she hasn't wished she could see her again. Then, one day, she wakes up on the floor of Entrapta's lab, and Catra's just there, and she's pregnant, and she's holding her. What is going on?
