The Half-Ender species are like the Ender species, but with more human features like the nose and mouth. Very few live to be a thousand years, but some have. Most live to 600-700 years, attacking the the other races too. The Half-Enders are more powerful than normal Enders, for they are less unpredictable and are always on the move. they never attack in the same city more than three times, they always add notes to their kill. A riddle. They do this to confuse the humans into thinking the riddle will help them. The riddles are actually there to stall time, to make the species even more  cofusing. The Half-Enders always mentally torment their victims. Making them go crazy.
