"It was a simple time; crops grew in the fields and people harvested those crops. Those people traded their goods to others who turned the crops into food. Everyone knew where they stood and what they owned and for the most part, people were happy. But they were also ignorant and as unfortunate as it might be for some, ignorance rarely lasts.
Torvala was a peaceful Kingdom but their people knew little about the world beyond their borders. There was no need for warriors, no need for weapons and no need for battle. They were sitting ducks when the Virani attacked. That is at least, until the Black Blade bonded with a Torvalan elf. Found in the darkest reaches of a cave never explored, the once abandoned mystical weapon called to a young farmer and willed him to venture into the darkness. Fueled by faith and a desperation to help his people, the elf made the journey accompanied only by his dog and two best friends.
Obviously you can guess the rest of the story. The hardships were immeasurable and the journey hard, especially on a peaceful people but they found the weapon and returned to the surface, ready to face the invasion. While the Virani warriors were far better trained, they were met with some resistance; the Black Blade was able to teach its new wielder and he in turn taught others. The society of the Black Blade was formed and, although the process changed dramatically during the Extermination, today the Black Blades form and protect those who cannot defend themselves. They are the ultimate heroes of Nerbys."
The Order of the Black Blade is a group of warriors who choose or are chosen by a powerful and sentient weapon as a bonded companion. The term Black Blade refers both to the weapon itself and it's wielder. The Black Blades have fluctuated in rarity over the generations of their existence and the location in question. Some places (like the Academies) stock pile Black Blades in the hopes of bonding a secret weapon. But there are still some scattered in the wild and, much like the original, they call to nearby people with potential and those brave enough to come to the call might bond.
Some Blades are pickier then others, much like a living breathing creature, they can be more specific int he warrior they are looking to bond with while others just want anyone willing to run into the fire. The Blades are nearly indestructible and after the death of one Bond, they often move on to a new one. Some Blades have a longer grieving process and others care more about being back in the action. Every Black Blade is different.
Despite their name, Black Blades do not need to be a bladed weapon. It is a common misconception, one that many Blades deal with regularly. They are, however, always entirely black. It is unknown who or what forges the Black Blades, as none of the weapons will speak of their creation and many believe they are left over from a time before the Divines. Some blacksmiths have been lucky enough to work with or study blades to learn enough of their properties to mend or fix broken pieces, because while they are indestructible, they do still take damage and loose effectiveness.
There is quite a bit of debate over weather a Black Blade (the person) is born or made. Some believe you either are or are not a potential (much like someone either has magic or does not) and others believe that if you train enough and make yourself worthy, a Blade may bond with anyone. It is all speculation.
