With the Heart of the Eternium in their care, the Guardians set forth into the multiverse, feeling both humbled and empowered. Each step they took resonated with the essence of the worlds they had visited, the people they had helped, and the bonds they had forged.

Their next destination was unknown, but they were no longer just travelers—they were the bearers of the multiverse's light, a beacon for those in darkness, a reminder of the power of connection.

As they walked through the portal, Kei, Teri, and Ignis knew that their journey would be endless, filled with challenges, triumphs, and lessons. But no matter where they went, they would carry the Heart of the Eternium, a symbol of the multiverse's enduring unity.

For they were the Guardians of the Fourth Wall, and their story had only just begun.
