Yeah, that's lifted.

>Go through the door on the right.

You go through the door on the right, and find... an elevator. It has two large buttons on it, UP and DOWN.

DOWN!!!!!!!! DOWN!!!!!!!!!!!!!!!!!!!!!! GO DOWN

>Go down

You go down. You notice it's beginning to get uncomfortably hot as you do so, and you step off the elevator. There's a passage down, one to the right, and one up.

Go closer to the passageways and see if it's particularly TOO hot going down each of them, and go through the one that's least climate-challenged.

>Check the passages

The passageway that goes down is far too hot to approach comfortably. You decide to go through the right passage instead.

Ahead of you looms a large lake, boiling and bubbling for a reason you're not entirely sure of. Across it is something you can't make out, while to your right is another door.
