"You have killed an enemy of the state, and may you kill a thousand more before you sleep. We all honor your glory, and we will drink to both!"
In order to obtain the title, one must make the killing blow against a dragon at least one size larger than they are, and have it be confirmed by a 3rd party source. On doing so, and having their kill known, they will forever be known as Dragonslayer.
Though primarily a symbolic title to show prowess, Kingdom of Cinerosa holds all dragonslayers to a higher honor, and keeps immaculate records of who is and is not a dragonslayer. Dragonslayers are counted as full citizens, are allowed to buy property within the kingdom, and allowed to run for public office, even if they live outside the city.
