There are rarely times when you do not hate being a SEA DWELLER. Being at the bottom of the hemospectrum is a death sentence, no more and no less, slower and more painful than being repeatedly keelhauled until your body falls apart. Some nights, you half consider slicing off your own fins. It won't change your blood color, but even trying to pass as a perpetually-stoned clown-worshipping SUBJUGGLATOR would be better than being a sea dweller.
But you'd much rather slice off the head of the next LAND DWELLER that looks at you funny.
