You are in the Graveyard Timeline. A place full of graveyards around with some trees. You saw a skeleton who wears a green military trench-coat with the symbol of The Royal Sky Guard. Additionally, she carried with her a massive toothed scythe that appears to be alive, which can be used to fly. Her most notable features are her neon green halo and wings that make her look like an angel.

Lucida: "Hey! Who are you over there!"

She saw you in distance.
