Split symmetry syndrome

The split symmetry syndrome as a birth defect afflicts the newborn with a condition where they are literally split in half partially and are mirrored horizontally. The condition may duplicate non-pair organs as well, like the heart, for example. People with this syndrome can be easily recognised due to a centered ridge stretching across their entire body.

The only two people whom the player may encounter in the game's current content who have this condition are Nkaanmykiunsuns and Vuisul. Their conditions don't seem to affect them negatively, but supposedly there have been worse cases with newborn babies whose splitting has been more severe and possibly fatal. It is unknown if the two aforementioned people were at lethal risk during their births and whether or not (and how) the split changed when growing up.

It is also currently unknown what causes it or if interspecies breeding increases the possibility of the condition occurring. Nkaanmykiunsuns's origins are unknown, and Vuisul is known to be a hybrid of two different species.
