Crux, "The Southern Cross" (クルックス Kurukkusu) is one of the Silver Key Celestial Spirits that is owned by Lucy Heartfilia.[2] It is unknown if Crux can be used for combat purposes. However, it is known that Crux has the ability to search for information about Celestial Spirits and their owners by sleeping, though he's forbidden to reveal too much, as one's activities are still a private matter in the Spirit World.[3] His full name is Crumudgeon.[4]


Crux appears to be an aged celestial spirit. His head beholds a giant, metal cross with floral-like golden patterns. He also has a white-haired mustache sprouting from his nostrils that also appears like tiny crosses. Oftentimes, he closes his eyes however, he will eventually open these if he found his objective. He seems to be wearing a medieval-like outfit, complete with green pants and wooden pointed shoes. His arms and legs are skinny, and appears to be tanned orange. On his arms are blue-colored knots attached to his wrists and elbows.

Crux is currently missing a tooth and he favors to levitate than to stand.


Crux doesn't talk very much. This can result from his restraint. He also often falls asleep.[5]


Loke arcEdit

Crux is summoned by Lucy to see if Loke had any history with a Celestial Mage before. During his meditation, he finds out that Loke once knew Karen Lilica but didn't divulge that Loke was really Leo.[5] He is later summoned again with the rest of Lucy's spirits to persuade the Celestial Spirit King to spare Loke's life.[6]

During the events near the end of the Grand Magic Games, Lucy has Crux look up information concerning the Eclipse Gate.[9] Crux delivers the results of his search to Lucy telepathically[10] as the gate is being opened, allowing her to realize where the dragons were coming from[9] and close it before any more got through.[11]
