The world seed

Liam, still wary but sensing the sincerity in the colossal whale's voice, hesitated for a moment before reluctantly releasing his hold on the guardian beasts just a little. 

As he did so, he felt the oppressive grip of the nether prison dissipate, freeing the guardian beasts from their confinement momentarily.

He could immediately see the beasts stand still as if they were lost in another world. Their crimson eyes were now pale white and they remained docile even if they were no longer under Liam's control.

"Now do you believe me?" The whale-like being spoke again. "I owe you an explanation but that can wait another time. I am sure you noticed it but these beasts are not themselves. They are corrupted. There is a complex magic at play here."

"It took me this long to wash off the evil that plagued me and my mind and I managed to do that only with the help of this world's blessing and the world seed fragment in your hands."
