"[Abyssal Seal]," I whispered, my voice barely audible.
The pen pulsed with dark light, and a wave of shadowy energy shot toward the core, wrapping around it like chains. The energy coiled tighter and tighter, locking the core in place as the [Abyssal Seal] took hold. The violent pulsing of mana slowed, and finally, the core settled into a dull, rhythmic pulse, contained within the dark tendrils of the [Abyssal Seal]. The oppressive weight of the dungeon's energy lifted ever so slightly, like a storm that had finally begun to lose its fury. My body trembled, my mana reserves nearly depleted, but I forced myself to stay standing. The danger wasn't completely over, but the immediate threat had passed.
Elandris staggered toward me, her hands dropping to her sides, the glow of her magic fading. Her usually vibrant and playful demeanor had dulled, replaced by exhaustion and relief. She wiped the sweat from her brow, casting a glance at the now-sealed core.
