The relation between dragons and their riders is the most unique in the history of Sekkai. Both are bonded beyond any means imaginable. The history of dragonriders goes back to the change in time periods in Sekkai, to 1 BR (Bond of Rider). After the many years of war between humanity of the dragons, a young female, in death, gave a boy her egg to care for, as well as a strange crystal. This boy became the first known rider.
The two are materially linked by the presence of a crystal. This crystal is embedded into the dragon's skin somewhere upon it's body, most often upon the chest or forehead. This crystal can only be broken by another dragon. Upon many occasions, such an act will result in the death of the dragon with it's cracked crystal. The rider also carries a much smaller replica of this crystal. This crystal is often worn on a chain, built into the hilt of a sword, or the likes, always close to the rider.
Dragons and their riders are also linked in their own brand of magic, spirit, and mind. They often know in some innate sense when the other is in trouble, though they are rarely able to communicate mentally. Both would be willing to die for the other and make any sacrifice necessary to keep their partner alive. In another strange manner, they often share the feelings of the other. When one is angry, the other may feel anxious and grouchy.
When either a rider or dragon dies, their partner need not do the same, though cases of ritualistic suicides are common. When the bond is broken, immense pain is felt, as well as a lapse of sanity. Though many regain this sanity, sometimes the mind is torn beyond belief and lost, never to return.
Dragons are usually taken in by a rider right after their hatching. For a few days they are referred to as Hatchlings, though once they move into their small group complex in the Academy, they become known as Wyrmlings. After hatching, Wyrmlings and riders are assigned their own quarters. Each quarter contains a 'nest' of sorts for the dragon, which is often made up of something relevant to their element. Leaves for a forest dragon, warm coals for a fire dragon, etc. The rider has their own bed, which is placed near their dragon. The aqueduct feeds pools of water into the room and drains it out. This is usually only washing water for humans, though for dragons it is often a ready source of drinking water.
Wyrmlings are graduated to Dragonlings once they have been placed in a Wing. Once they are near maturation, they are again reclassified, this time as mature, and they lose the titles of wyrmling and are allowed much more freedom.
