That was when he had just been affected by the impurities in his body and degenerated into a Stray Beast.
Because Stray Beasts were uncontrollable, he deserted his tribe and fled to the Central Wilderness. Isaac, wanting to stop him and worried about him, chased him into the Central Wilderness.
At that time, the Central Wilderness was even more chaotic and filled with bloody violence than it is now. Isaac clashed with Stray Beasts several times as soon as he entered.
He was weak and stood no chance against these violent Stray Beasts. He could only look for opportunities to escape.
And that was how he unintentionally entered the ruins of the Beast God Hall.
Chelms only found out that Isaac had chased him five days after he himself had entered the Central Wilderness. By then, he had regained a bit of clarity and followed Isaac's scent.
He only saw Isaac lying at the gate of the abandoned Beast God Hall ruins, with not a single living creature around.
