As a baby, Crowley was left in a basket in the woods. Despite there being wild animals present, he was protected by the spirit, [[Korozo]], until he was found by a [[Crowley's grandfather|retired scholar]], who assumed the role of a surrogate grandfather.<ref name="cp 2">{{chapter|Yu-Gi-Oh! OCG Stories|Magistus|2|ref}}</ref>
Korozo, who was only visible to Crowley, stuck with him through his life. Crowley would sometimes be mistaken as being talking to himself when speaking to Korozo and some people would dismiss Koroza Korozo as being imaginary.<ref name="cp 2" />

Crowley and [[Rilliona]] were both scolded by Endymion later for each interfering with his experiments. Shortly after, Crowley questioned if the others had felt that the flow of magic power had become much more unstable recently. He explained that he was studying "invocation summoning magic"; and that he follows the path of magic power that flows into this world and summons forth spirits from another world. He theorized that there are two types of magic power; one that forms from life energy and one that flows into this world from another. However, Endymion thought the ideas of another world and summoning spirits were ridiculous. Crowley tried to argue that such spirits were real, citing Korozo as an example, which Endymion dismisses as being an imaginary animal. [[Zoroa]] and [[Spoon]] were more open-minded to Crowley's ideas and the importance of investigating all fields of magic. However, Crowley fell asleep at this point.<ref name="cp 2" />
[[File:Cocytus fused.png|thumb|left|x300px|Crowley inadvertently aids in Cocytus being fused]]The next day Crowley was awoken by Coroza Korozo who noticed some strange magic power. Accompanied by Endymion and Rilliona, Crowley traced the source of the abnormal magic power to a dried-up spring in the forest. Crowley suspected the magic power was from another world and attempted to contain it with a magical circle. However, this caused the tadpole-like shapes within the magic power to fuse and form , [[Cocytus]], a spirit summoned from another world. Crowley was happy to have his theories proven right, but the spirit proceeded to attack them. Attempts to fight back were futile until Koroza Korozo absorbed all the other-world magic power, causing the other spirit to disappear and Koroza Korozo to change shape. Koroza Korozo reverted to their normal form shortly afterward and collapsed into Crowley's hands.<ref name="cp 2" />
Events Crowley caught [[Lopo]] off guard, while Lopo was observing Graybeard with a pair of binoculars, causing him to fall from a tree. Crowley asked if he was okay and if he had business there. Lopo insisted he was not doing anything, but begged Crowley not to tell anyone he saw him before running away.<ref name="cp 3">{{chapter|Yu-Gi-Oh! OCG Stories|Magistus|3|ref}}</ref> Endymion sought advise on his magic from Crowley and dragged him to a large boulder that he proceeded to damage with his lightning-based "Thor Hammer" spell. Crowley was critical and explained that transpired eventually resulted elemental magic is about the right person being in the right place at the right time with the right climate and terrain. To illustrate, he pointed out that there was wind blowing in the forest and cast his wind-based "Cyclone" spell, which completely shattered the boulder. As Crowleyshared his lunch with Endymion and Rilliona, they were attacked by Lopo who was being controlled by evil magic from another world. Endymionmade use of what Crowley told him about effective use of elemental magic to burn away the evil magic, returning Ropo to normal. Crowley was impressed, but concerned about how the magic power had so easily leaked in from the other world.<ref name="cp 3" /> [[Rilliona, and Zoroa all becoming ]] showed a [[Magistuscrystalline meteorite]].

Crowley recognized the mountain in the image and Spoon was able to create a portal to take them all there. Crowley complained about the cold, but sensed a great magic power, which the group followed into a cavern, where they found Theurgy,<ref>{{chapter|Yu-Gi-Oh!

This was to result in a flow of magic power into their world. Crowley, Rilliona and Endymion attempted to combine their powers to close Theurgy, but were confronted by Zoroa. Crowley and Endymion pointed out that the flow of magic power would result in many deaths and Crowley asked what happened to the Zoroa they once knew. He replied that the search for truth trumps all and that that he thought Crowley of all people would understand that. Unable to reason with him, they prepared to fight and Crowley was excited by the prospect of battling such a powerful spellcaster. Zoroa attacked the trio and they fought back by calling on their guardians deities to grant them power. [[Aiwass]] was called in the case of Crowley.<ref name="cp 1" />
