Hannah and Luneria began to focus on using their powers at the same time while drawing the mana from the golden crown. Before long, the air around them began to vibrate.
All of a sudden, an ominous rumble reverberated through the entire facility. The walls shuddered, and the ground beneath their feet quivered with a disconcerting intensity. Equipment rattled, and loose objects clattered, adding to the cacophony of the trembling environment.
Amidst the commotion, the space in the middle of the group, where their combined magic intertwined, began to crack. It resembled a fragile pane of glass splintering under immense pressure, spiderweb-like fractures spreading outward with each passing moment. The cracks snaked through the air, distorting the surrounding space with an eerie, ethereal glow.
When the first cracks appeared, the group began to feel some shivers. They could feel some crazy amounts of malevolent energy beyond the cracks.
