Grave Dragons are not named for their connections to death or burial, but for the grave expression on their faces. This strange expression is used as a defense mechanism that causes fits of panic and terror in potential predators. Since they only eat ash and charcoal, they do not hunt. Grave Dragons are powerful fire-breathers and have been known to burn down forests and villages alike to make meals. It is believed that the markings on each Grave Dragon’s wings are the faces of those who have lost their lives in fires started by that dragon.

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.

Crypt is a female Grave Dragon under the command of Vendetta. Unlike her leader, and most of her groupmates, Crypt is not very malicious. She isn't as cruel as Demise, or as creepy as Roulette. But she's also not as friendly as Waylay. She's quiet and polite, though given the other Grave Dragons' reputations she is often classed as wicked as them.

Preferring to sit back and watch the events pass by, Crypt rarely involves herself in activities or conversations, mostly due to the fact that Vendetta seldom allows her inferiors to mingle with non-Halloween Dragons. The same boring, repetitive drama that the cave's Halloween Dragons constantly partake in overwhelms Crypt.

Although she doesn't reveal much thought, Crypt seems to thoroughly enjoy the autumn months, specifically October. While she's only lived through one Halloween the female Grave shows no doubt that she's already set for the next.
