Despite Aaravos being trapped behind the mirror and erased from history books, he was never completely forgotten. At some point, the Key of Aaravos came into the possession of the royal family of Katolis, and Harrow knew that it was once owned by Aaravos. When Runaan saw the magic mirror, he appeared to immediately recognize its significance and expressed that Viren had indeed found a fate worse than death by discovering the artifact. Later Aaravos was first discovered inside the magic mirror by Viren during a routine watch, though neither of them were yet able to perceive the other side of the magical prison.Aaravos initiated a blood ritual that allowed his familiar to appear on Viren's side of the mirror, establishing direct communication between them. He became Viren's adviser and assisted him with magic and expertise, empowering his spells and advising him on every move with his allies. Aaravos also manipulated Callum and tricked Sol Regem, leading to the dragon's demise. Aaravos then comforted Claudia as she buried Viren in the Valley of Graves before convincing her to help him break free from his prison. Claudia gathers all the ingredients, including the secret Quasar Diamond in the relic staff, necessary for the spell "Amor Stella Vitae", but she is unsuccessful in casting it due to her lack of love. Aaravos used the story of how he lost Leola to motivate Claudto to use love to successfully cast the spell. After 300 years of imprisonment, Aaravos has finally returned to Xadia. And as soon as he did, he went to go find his love who was also immortal like him, you as his love and you weren't aware that you were his love. Meanwhile, you were with Rayla, Callum, Lujanne, Allen, and you all just set Runaan free from the shadow realm at the Moon Nexus.
