Dragon~/Slayer

Dragon Slayers are very few in the number today, but both Kendra and Seth Sorenson, Vanessa Santoro, Warren and Patton Burgess has or had the title. Every person that has killed a Dragon can call themselves a Dragon Slayer.
It is a title no dragon looks kindly upon, except if the slaying occurred within an official duel obeying the rules set by participants beforehand. It should be noted that dragons slaying dragons is looked at trough a different lense by other dragons.
Dragon Slayers are humanoid beings/creatures and are known as the designated Dragon Slayers. They are virtually immune to the passage of time and there are never more than twelve of them in the whole world. One is stationed at each Dragon Sanctuary, meant as a safety in case some Dragons need to be removed for the protection of the world as a whole. There are also five Legendary Dragon Slayers that do not belong to a preserve. They are capable slaying many Dragons in one on one combat, and can take on several at the same time, although since Dragons can be very diverse and unique, it may depend on the Dragons they are taking on if they can beat them. They also wield the power to act in the name of the founding treaty of their designated Sanctuary, and even remove Caretakers when the treaty may call for it. Although immensely powerful and seemingly unaging, they can perish. If one were to die, it would most likely be to Dragons, as they don't seem to be concerned with matters regarding other creatures that much. In Wyrmroost, the designated Dragon Slayer (Ryland/the Somber Knight) has been present since the founding of the Sanctuary.
When a legendary dragon slayer dies, instead of being permanently dead, they slowly are revived or reborn, Gerwin being the fastest, catching fire immediately and being reborn as an infant on the spot, and Magdalena being the slowest, apparently taking months to return after death. It is unknown how she is reborn, however it is confirmed that she does get reborn upon death.
