As they ventured deeper, they stumbled upon an underground chamber, its walls lined with glowing crystals. In the center of the chamber stood a massive stone monolith, covered in ancient runes and symbols.
Dr. Hargrove approached the monolith, his eyes wide with wonder. "This is incredible. These runes are similar to those we found in the hidden chamber, but they're much older."
Nefertari examined the monolith closely. "The energy here is intense. It's possible that the Heart of Light's activation resonated with this monolith, causing the tremor."
The team spent days studying the monolith and the surrounding crystals, trying to understand their connection to the Heart of Light and the island's balance. They discovered that the monolith was an ancient artifact, a keystone that helped regulate the island's energies and maintain its stability.
