Turpentine Dragons are named for the oil that covers their scales. This oil resembles turpentine in odor and is mildly toxic; it will not kill but it burns to the touch and will cause illness in anyone who ingests it. Turpentine Dragons roam in large packs, often stealing food from larger dragons, though they are able to hunt for themselves if necessary. Many other breeds consider Turpentine Dragons to be pests, so they primarily breed among themselves.

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.

Acid was the founder of the Zombie Project, as one of the first scientists to start looking into the mysteries from beyond the grave. While he did not have the skill of Twisted, the intelligence of Artemis nor the logic of Cimin, Acid was the pushing force behind all of this, bringing the team together and making the difficult decisions that nobody else wanted to do. Acid went through the pain of choosing the victims for the project, dealing with the fallout as the general population discovered this, all for the sake of science of course. The stress of being the lead turpentine, and running such a time consuming project got to him, and upon seeing the grander plans for the second Zombie Project, bowed out of the main project, instead becoming the negotiator between the project and the council. While he finds this job much less demanding, he constantly worries about the condition of those who are being experimented on, and deep down, misses his old career dearly.
