The Orion Coin is one of the one hundred Constellation Coins scattered all over the world in Endless Ocean: Blue World. It is a necessary item needed for the completion of the Voice of the Night Sky quest. This coin can be found in Ciceros Strait within Valka Castle, in a zoom-mode glow in the floor of Spiral Tower. As well as this coin, the zoom-mode glow is also home to a pair of Luminescent Sea Slugs.
- The Orion constellation (home to the famed Orion's Belt, a row of three very bright stars in the night sky) is meant to represent the hunter Orion from Greek mythology.
- In the mapping of constellations, Orion is sometimes related to the constellations surrounding him: He is standing by the river Eridanus with his two hunting dogs Canis Major and Canis Minor, facing down Taurus, a wild bull. Sometimes, he is depicted as hunting the rabbit, Lepus.
