From MC's perspective:
Meiron Wilderness-Cliff,
Theo and others are following that narrow path. The place is dark. But because of their magic level, their vision is many times better than regular humans.
They find no trouble in following the path. But not long after, the group heard a loud hissing sound.
Hiss!
"What is this sound?" Tim asked. So far they didn't face any trouble.
But this sound made them alarmed.
Theo's eyes flickered. He thought that the monster's lair was empty. But it looks like some other monster has occupied it.
Then he looks at Tim and Ronnie. A cunning glint flashes in his eyes. He is going to use them as cannon fodder.
On the other hand, there are several black snakes with purple eyes moving towards the intruders. This particular black snake monster likes to stay underground.
