There comes a time in every Avatar's life when he must make universe-changing decisions.

But what if he didn't?

(Sequel to Broken Blade.) Jeralt had stayed at Garreg Mach Monastery rather than fleeing after the fire twenty years ago. Byleth was raised within the embrace of the church, his knowledge and form molded by a new upbringing. "My name is Sothis," the girl inside his head said. And he could not help the surprise at hearing the goddess's name.

Ingrid resented her father's attempts to use her as a pawn to restore the glory of their house. If she were to marry, it would be for love, not prestige. At Garreg Mach Monastery, she'd find what she was looking for.

Delthea knew two things for sure: she was a gifted Channeler and this was NOT the adventure she was looking for. She wanted to go see the world beyond her village, not be tied down at some academy! Little does she know, her eyes are about to be opened to a world far greater than what she bargained for, and it all starts with a boy who has a habit of talking to himself… (Modern AU)

I've read several stories about people waking up and finding out that they received the abilities of a Gamer through mysterious means. I never expected to become one of those people. Nor did I expect to wake up in a field in Ylisse, of all places. Well, you know what they say. When life gives you lemons, make lemonade. Rated M for safety.

The night after Miklan dies, no one can find Sylvain.

Bernadetta runs into Dedue in the greenhouse and realizes he's not as intimidating as he looks. FE16 one shot, non-route-specific.

"She looked at the people of her tribe, all bones and anger from the hunger. She looked at her husband, with his thin face and the quiet resignation in his eyes. She looked at their daughter, a miracle for having survived to four years old with the way things were." (Chief Rinkah vs. a man-made famine.)
