Dorsal Dragons are so named because they have large fins along their backs that can be raised and lowered at will. They use these fins to regulate body temperature; they raise them to cool off when they become overheated. The bright colors on the fins double as a means of attracting mates.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons 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. In Galsreim, dragons and humans coexist peacefully.

I Am Paranoia is aptly named; he is so strongly gripped by the debilitating paranoia which plagues him that it almost entirely consumes him. Terrified of everything and everyone, he is convinced that anyone who approaches him must be a demon in disguise. It is said that something dreadful happened to Paranoia in the past, an ordeal so terrible as to scar him for life; no-one can be certain exactly what he went through, but there are many dark rumours circulating the Cave about forbidden fruits and long captivity. Whatever happened to Paranoia, the illness which gave him his name holds him captive still. Sometimes he becomes so frightened of the entire world around him that he simply cowers at the back of his cave, only kept alive by kind-hearted White dragons who leave food outside for him. When Paranoia finds the courage to face the outside world he often sings with the Vocaloid Clan. His song, Paranoid Doll, spins a disturbing picture of what it is like to suffer from mental illness.
