Yeah, I can also imagine plenty of traps laid out within the cave waiting to be unleashed if any of us does make a mistake or mishap. Some are hidden and others are out in the open.

(Harry has dealt with his fair share of dealing with traps both at home and in Avalon. So he is not too surprised if he does come across a couple in the cave.)

And oh, right, the lava: hot rivers of lava twisting across the cave too. Considering that this mountain is also an active volcano, it is possible that we might run into them during the ring search.
