Dragons are creatures with nearly unlimited life spans. They can survive for long periods of time, and no one has found a dragon that has died of old age. Adolescence is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. Once they hit adolescence, hatchlings change quickly, maturing to their full forms in only 2 years.
Dragons don’t communicate with each other verbally, but they will growl to scare off predators and frighten prey. Young dragons will emit an extremely high-pitched squeal when they are frightened. To communicate, they use telepathy with each other and to speak to other creatures.
Magma dragons are capable of withstanding the intense temperatures of their element. They live in volcanic regions, their bodies coated in the red hot magma which clings to their scales. They must leave the lava fields in order to hunt, although they require surprisingly little food to sustain their lumbering mass.
For a time, this Magma was homeless, unable to find a volcano that was uninhabited. Her travels brought her, nearly solid stone, to the canyons run by the Stripe, GLaDOS and other dragons of the Aperture Science (or, more commonly, ApSci) clan. She was given a choice- either do as GLaDOS said, and get a home, or be back on the road. Incinerator opted to stay, making her home in a lava pit in one of the cave systems. In return, she has to do one thing- keep the pink, Companion Cube Dorkface, confined to a single cave. This was achieved by burning the Pink so badly, she developed a severe phobia of fire, and Incinerator herself.
