The temperature inside the cave increased after every step Arthur took. He couldn't understand how a volcano was there, in the middle of an immense Elven forest. It did not fit the vibe, but who was he to ask?
Arthur had only one goal in mind, and that was to find the Lava Worm and kill it. In his mind, it wouldn't be a hard fight considering his fire resistance, and his high attributes that were more like a cheat.
A cave that not only kept increasing its temperature, but got narrower, giving a dreadful feeling. Also, there weren't any living beings inside of it. All Arthur could hear was his breathing, and that wasn't comforting at all.
It was at that moment, after walking for about 10 minutes, he saw it. A pit of lava, and a creature laying above it, asleep. A worm that was almost transparent, and with visible lava inside its body. About 17 meters long, with sharp long teeth in its mouth, but no eyes.
