Draco Stellarum
The Draco Stellarum (known colloquially simply as "the dragons") are a species of carnivorous aliens from outside the Milky Way Galaxy. They were first discovered by the USS Columbia on stardate 239001.15, after having travelled to Odyssey Station through a black hole.
In general they are roughly dragon-like in appearance, though their physiology is anything but dragon-like.
Biology
Puberty
Unlike most species puberty for dragons is not a process of attaining the ability to reproduce. Rather puberty is a rapid and often violent change from being a juvenile dragon to an adult.
Reproduction
Not much is known about dragon reproduction. However it appears that dragons do have a concept of parent (for example, Puncdor's mother) thus hinting at sexual reproduction.
Environment
The dragons are a space-borne organism. Their advanced physiology and bizarre forms of travel hint at an evolutionary history unlike our own and probably aided artificially.
Dragons are also able to travel through certain spatial phenomena without injury. Puncdor used the term "dark space" for "black hole", and seemed more than happy to travel through the phenomenon, while most species would consider a black hole to be certain death. It is apparent that dragons are capable of faster than light travel by means of bending space time around themselves. The means by which they do this are not well understood.
Culture
Dragon culture starts and ends during "childhood." Here childhood is understood not to mean immaturity but rather a literal precursor to adulthood. For dragon culture the attainment of adulthood is tentamount to the death of the individual as a member of society and the promotion of that individual to the status of defender of the culture. The fully grown adult then becomes a carnivore and feeds on creatures referred to as "Evastock and the Korbastik." Nothing is known of these entities aside from their being mentioned by the Dragon Puncdor.
