A Vascoreon dragon.
Usually calm, but he gets furious, sad, heppy or others quite quickly in certain situations. He feels protective for his friends and siblings as he is the oldest, and cares for them almost as much as does his mother.
He can use water magic best, but also a bit of energy. He can fly and move around quickly in air as he can in water. His skin is very soft and his scales are not very resistant, so he has developed a spell that allows him to change to water wherever he is hit physically, but this takes much energy to do.
Born as the grandson of an Elder Dragon, Delta was quickly well-known aslthough he did not do much. He became more of a dreamer than many others as it is the nature of many Vascoreons, and passed most of his time in a cavern which he had found someday. As he grew older he became more present though, and envied some of his friends which has The Link towards an elf. He knew though that he would someday gain The Link too.
Due to a trauma which he suffered during the Great Dragon Exodus (he had seen aggressive humans, and was wounded by swords and arrows multiple times) he enters a trance-like state as soon as he sees a human, then attacks that person as long as he can see it. He can not remember anything afterwards.
