Pyxis

Pyxis, "The Compass", is one of the Silver Keys' Celestial Spirit that is owned by Lucy Heartfilia.

Appearance
Pyxis has a great resemblance to that of a bird, it has wings and a beak. Pyxis also has beady eyes, a tubby body figure, and small yellow feet. It has diamond-shaped patches located mostly on its torso. Pyxis most distinctive feature is the large blackish-grey compass on its head.

Grand Magic Games arc
A key to Pyxis' gate eventually came to the possession of Celestial Spirit Mage, Lucy Heartfilia who formed a contract with it, the details of which are unknown. At the Sky Labyrinth, during the preliminary round of the X791 Grand Magic Games, Pyxis is summoned by Lucy who instructs it to direct them to the east, in order to get to Domus Flau. Pyxis points towards east and the group follows its direction but the group quickly finds themselves lost as navigating the labyrinth isn't such a simple job.

Magic & Abilities
Directional Reference: Pyxis has the ability to tell directional references. When it does this, the compass on top of its head spins until it stops and Pyxis points the way with both of its wings.

Immortality: As a Celestial Spirit, Pyxis cannot die, unless it is forced to stay in the Human World somehow.
