False-Headed Hydra Dragons actually only have two heads. Despite their appearance, their tails are pure muscle and lack any internal organs. In combat, their false heads are used to bait their enemies into attacking their tails instead of their more vulnerable heads, creating openings to strike back. These dragons have been known to frighten and intimidate other species by holding their tails close to their necks, making it look like they are a larger, more threatening four headed beast. They also use their tails to help them hunt their prey, confusing their targets in various ways. Their scale coloration and hunting habits vary depending on their environment. False-Headed Hydras can regrow their tails if they are cut off or badly damaged.

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.

Two-headed dragons are unique enough to deserve a separate classification from ordinary dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, snapping back and forth. Their unique anatomy prevents them from breeding with single-headed dragons.

Length and Strength is daring, adventurous, formidable, and surprisingly amendable to performing research, even research that involves no fires and stuff that goes boom. Length is very talkative and has a damaged eye, and Strength speaks with a purr and has a greater sense of competition. They can be seen working for the Grape Visitor Center, giving tours of the city. A lot of the stuff they say about current events in Grape are made up for their amusement, though they never lie about its history. Length and Strength may look youthful, but the stuff she says and the breadth of knowledge about how Grape, Zimring County and Galsreim used to be suggest she's at least 600 years old. Sometimes, during a tour, someone accompanies her to take notes on what she's saying so this information wouldn't just reside in her brains. She doesn't seem to mind, though Strength might ask for greater compensation. When asking followup questions, people have to make sure they talk to the right end.
