All around you is solid lava, as the tunnel seems to be formed completely
of molten living lava.  It is warm to the touch, and yet some invisible
force prevents you from fully touching it.  Formed into a vaulted ceiling
many saplings tall, the living molten rocke flows freely around you. 
Strange creatures seem to swim in the molten walls, occasionally taking a
small peek at the strange creatures walking through.  Small alcoves and
outcroppings line the passage, creating various hiding places for strange
underground creatures to hide.  
    You sense a hidden life form in the area.
