**Chapter 38: Celestial Sacrifice**

The Twin Travelers' journey led them to Sumeru's ancient halls, a realm where knowledge and enlightenment flowed like a river of wisdom. Here, they encountered Oziel—a historian with a connection to the Dendro Archon and the echoes of selfless sacrifice.

Oziel's presence carried the tales of sacrifice that had shaped Sumeru's identity—a realm where individuals had given of themselves to protect the realm's essence. His stories unveiled a narrative of selflessness, where individuals had placed the needs of others above their own, weaving it into an unbreakable tapestry.

Through Oziel's guidance, the travelers journeyed through Sumeru's history of sacrifice, tracing the bonds that had shaped the realm's identity. They learned of battles fought against selfishness, battles that had defined Sumeru's legacy and the selfless acts that upheld it.

Yet, amidst the realm's intellectual pursuits, they sensed a void—an entity known as the Eclipsed Martyr, a force seeking to sever the connection between sacrifice and legacy. The travelers recognized that their journey extended beyond observation—it was a mission to preserve the echoes of selflessness and unity that had shaped Sumeru's identity.

With Oziel's guidance and the echoes of those who had given of themselves, Lumine and Aether embarked on a journey to defend the bond between sacrifice and legacy. Their battle against the Eclipsed Martyr was a testament to the power of selflessness, unity, and the unwavering determination to protect the legacy that had woven Sumeru's past and present into an unbreakable tapestry.
