As Erik and his companions delved deeper into the mysteries of the lost city, they came across a hidden chamber that contained a portal. This portal, the Ancients explained, was a gateway to the Celestial realm, a parallel dimension where time flowed differently and the laws of magic were more potent.Curious and eager to uncover more secrets, Erik and his companions stepped through the portal and found themselves in a realm unlike anything they had ever seen. The Celestial realm was a place of ethereal beauty, with floating islands, shimmering waterfalls, and skies ablaze with color.However, they soon realized that this realm was not just a place of wonder, but also a place of trial. The Celestials had left behind a series of challenges, each designed to test the resolve and strength of those who sought to unlock the secrets of their civilization.The first challenge they faced was the Trial of Elements, where they had to navigate a series of elemental puzzles and challenges. With Elara's mastery of magic, Naida's connection to nature, and Erik's demonic abilities, they were able to overcome the challenges and move on to the next trial.The second trial was the Trial of Knowledge, where they had to solve riddles and puzzles that tested their intellect and wisdom. With the help of the ancient texts they had discovered in the city's library, they were able to decipher the riddles and unlock the secrets of this trial.The final trial was the Trial of Courage, where they had to face their greatest fears and doubts. Erik, Elara, and Naida were each confronted with illusions that tested their resolve and forced them to confront their inner demons. Only by overcoming these challenges were they able to complete the trial and move on to the next phase of their journey.As they emerged from the trials, they were greeted by the Ancients, who congratulated them on their success. They had proven themselves worthy of the Celestials' legacy, and now it was time for them to uncover the final secrets of the lost city and fulfill the prophecy that had brought them here.
