Sebastian wasn't able to save her. (During CoLS, when Clary followed Sebastian in Paris.) Here is another take on that scene.

Thousands of years ago, this ruined world was reborn into one of magical races. Elven princess Lucy Heartfilia is injured during an attack on her kingdom, only to be rescued by a strange boy named Natsu, who's been looking for her all his life. Will their mission to uplift a falling world succeed? Rating/Genre subject to change. AU. Adaptation of locoanime's "The Phoenix".

For the first time, Aries reveals exactly how Karen Lilica died. A certain lion spirit comforts her, and they resort to wistful conversation. Both will make a confession or two.

Natsu, having nothing else to do, asks Erza for advice. Unfortunately, she has none to give. NaLu one-shot.
