The Covenant of the Rose, is the governing institution of an organization dedicated to the fight against vampires and demons. Despite their status as assisting Undead Slayers, over the years the Covenant has become increasingly arrogant and egocentric, believing themselves to be the supreme authority while the Slayers are just their tools. The Covenant of the Rose has been known to use ethically questionable methods to accomplish its goals, such as interrogations, smuggling, and, if necessary, assassinations. The Covenant is also known for placing its principles and perceived goals ahead of the well-being of the Slayer. It mainly finds, trains, and supervises Undead Slayers. The Covenant's main headquarters is in London, England. It tries to locate potential Undead Slayers and then sends Monitors to inform and train them. It is not always successful in doing so, and therefore some Slayers are fully trained when they are called, while others know nothing of the heritage or purpose of their power. Each potential Slayer is assigned their own Monitor – a Covenant employee who is responsible for training the Slayer in combat techniques as well as researching demons, vampires, and magics. Monitors also maintain diaries chronicling the lives of the Slayers under their charge.
A standard Monitor has at least some proficiency in the
use of magic with certain individuals being more powerful than others. Numerous
members are alchemists. They are students of demonology and as such have a wide
knowledge of various incarnations of evil, but their expertise is usually the
vampire. They are also highly educated and can speak a wide variety of
languages, both human and demonic in nature. Monitors are typically well versed
in hand-to-hand combat techniques, though they generally confine themselves to
training Slayers or supporting them in battle, as their relatively lower
strength limits their effectiveness in directly engaging vampires.
