Wonder why the FOV is so short
You have no idea what that is. Does it mean Fall of Velocity? You did just fall at quite a velocity.
(OOC: I'm playing at FOV: Normal.)
Look around in all directions, and attempt to make sense of where you are now.

You appear to be in an enormous, lava-lit cavern. You can only see the wall in front of you and the ceiling about you, and the floor below you is glass directly above lava. The wall you saw was completely stone with no ores or cobblestone on it.
You feel like you should remember this place, but you don't.
walk to the wall and follow the wall to find a door or something

You don't follow the wall for fear you may get lost, but you do pass through the pool after looking around and can see an enormous stairwell going directly up.
