Background
Velgaia has a long history as it originated as Star King Dragon Veldanava. After Veldanava died he was reborn as Gaia, who became Milim's pet dragon.

When her pet dragon was killed Milim was sent into a rage and ascended to a True Demon Lord and had to be subdued by Guy Crimson and Ramiris. When Milim evolved the Gaia's body transformed into a Chaos Dragon. However, since it did not have a soul, the dragon transcended both good and evil becoming a force of pure destruction.

Milim in her sadness sealed Gaia's body away so that nobody could find it. However, the dragon's energy slowly seeped from its body and ruined the surrounding nature. When the Freedom Association was asked to investigate the miasma, Yuuki found the Chaos Dragon.

During Leon and Yuuki 's battle, Yuuki summons the Chaos Dragon that was previously sealed by Millim. Upon it corroding everything around them using Chaotic Breath, Leon quickly seals it with a Holy Attribute Barrier that is much stronger than the Hero's, Infinite Prison, but not before Yuuki has stolen its dragons core (power) and becomes a Dragon Warrior. Yuuki is now covered by the same miasma that once covered the Chaos Dragon, resembling an ominous black armor resembling scales. Without its core, all that is left of the Chaos Dragon is bones and ash. Even with Yuuki's increased strength he is worthless before Leon's might and loses an arm. In this beaten state, he escapes before he is fully engulfed.

Inside the Red Knight, two souls were found by Rimuru and company. One was of the Red Knight herself and that of the Chaos Dragon, which has now been purified by Leon's previous attacks. With Ruminas help, the two souls are separated and the Red Knight is revived with the core of the dragon being placed into a jewel in the keeping of Rimuru, however, in doing so Gaia's power was greatly weakened.
