Blood

Blood defines the races in Vartarra. There are 3 blood types, cold blooded, warm blooded and hot blooded. Hot blooded is the rarest and gives an immunity to almost all damage from heat, however it means you have little existence to harsh cold. Hot blooded people can also be identified by a glow behind the eyes. Warm blooded is the most common type, and means you can adjust to most climates. Cold blooded means a resistance to the cold, however little defense from extreme heat. A races blood type does not specifically define its habitat however, as Dwellers can live in climates like the East or Andur.
