Aiden stepped forward to deliver the final blow to the goblin lord, his sword raised high. With a fierce shout, he brought the blade down onto the creature's skull, ending its life with a single strike.
The goblin lord let out a final, agonized roar as it crumpled to the ground, defeated. Aiden took a moment to catch his breath, his heart racing with adrenaline.
Once he had recovered, Aiden went to inspect the goblin lord's body. He knew that these creatures often carried valuable monster cores, and he was eager to claim the prize.
As he searched the body, he found what he was looking for - a large, pulsing gemstone lodged in the goblin lord's chest. This was the monster's core, the source of the creature's power.
Aiden carefully extracted the core from the body, his fingers brushing over the smooth surface of the gemstone. He could feel the energy coursing through it, and he knew that it was worth a small fortune.
