Hourglass is one of the 13 fragments of Meta, the denizen deity. She is also one of the four siblings, represented in the puzzle piece as the purple side. She is also represented as an alpha symbol in the drawing known as "Corners". She represents order and balance and is Paradox's opposite sibling.
In the chess game, she is not a player or a piece but is actually a rule enforcing mechanism of the universe and the chess game.
Hourglass is currently deceased due to Ember's death, along with Paradox and Vortex. Her dead body is at autumn twilight, on the right side of the big purple portal in the form of a cloud.
