It doesn't look like a final room of quest, eh? Just like a short cave between two different caves.
And yes, we won't be able to see most of the lava. So why is lava placed here? If author decided to place a lava, I suggest him to detail it a little bit. Anyway firstly you are hating him, and then you are protecting author. Why? I think that this cave is pretty good as for amatheur, so I just gave him a little suggestions, what he could modify in details. Soo stop being so smart, ok? Geez, you truly are a difficult person.
