Destroy the grate and swim through it
You seem to be in a small tunnel. The water isn't as cold here as it
was in the castle pool. You're still low on air. After swimming out
of the tunnel you look up and you see light shining down through the
water. You swim upward and finally reach the surface.
GASP!!!
It feels good to get a breath of air in your lungs after that
experience. After catching your breath, you notice where you are.
You're in a well made of stone. The water doesn't reach halfway up
it. You think you hear voices. Maybe you could call for
help.
You grab your sword with both hands and cut through the wooden grate.
Around 400 fish swim out of the grate and swim right by you. It feels
like you're in a kalidoscope with all the different colors going by so
fast. You put your sword away and swim through the grate.
