The chamber was a maelstrom of energy and chaos as Elara and her companions battled the shadowy figure that had emerged from the altar's corruption. The dark entity moved with a fluid, nightmarish grace, its tendrils of darkness whipping through the air, each strike carrying a chilling cold that threatened to sap their strength.
Elara's sword blazed with a fierce light as she engaged the figure, her strikes precise and determined. The blade cut through the shadowy form, but the entity seemed to absorb and regenerate from the attacks. Morgana and Selene chanted their spells, their magic weaving through the air in an intricate dance of light and power. Each incantation and rune traced by Morgana created bursts of energy that disrupted the dark figure's cohesion, while Selene's beams of light cut through the surrounding shadows, providing critical support.
