Amelia Croft (Legend Timeline)

Lady Amelia Croft, née DeMornay, was the wife of Lord Richard Croft and the mother of Lara Croft until her disappearance when the family's plane crashed on The Himalaya mountains in Nepal when Lara was young.

Fate
Her fate is unknown, however in Tomb Raider: Underworld after searching for her lost mother Lara finds her overlooking the Sea of Etir, after Lara calling her Amelia Croft turned around, it wasn't till then that Lara saw her mother had half her body turned into a thrall, Lara said 'you are not my mother, my mother died a long time ago' just before shooting her off the edge and into the Etir.

It is unknown whether Amelia Croft was or was not a Thrall.

Later, Lara and Amanda pulls on the same sword that Lara's mother used and go to Avalon. They come out the other side, presumably where Lara's mother did. Amanda is about to kill Lara but Lara convinces her it would change nothing, so Amanda leaves. There is a skeleton on the floor next to where Lara is standing, and Lara assumes that Amelia tried to use the other portal to escape but didn't know how to use it. Lara bids a final farewell to her mother and leaves.
