The Teevans are a humanoid species that made contact with humans in 2476. Their medical knowledge is more advanced, however, as they can reanimate someone who is dead for more than two weeks. Teevans also have high regards for every life which is honored by the saying "Never harbor anger towards those who have brought you death for they gave you the chance to live again." Teevans do not procreate to obtain offspring like other species; they salvage dead sentient lifeforms which they reanimate. Over a period of several months, the DNA of the reanimated lifeform is altered by means of a genetic pathogen that converts most of the DNA into a Teevans protein structure. These biochemical changes affect every part of the body, leaving only trace amounts of the original DNA. After this, they are given Teevans names and placed in Teevan families to help them acclimate. Some Teevans joined human society and created another race of Teevan Hybrids.
