Thunder Dragons are the masters of electricity. Their wings gather energy as they soar through the clouds, and when they clap their wings together they can create devastating arcs of lightning. They can stay airborne nearly indefinitely, landing only to sleep and breed; they catch their prey from the air and take moisture from the clouds. A thunder dragon’s roar is considered to be an omen of misfortune.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

As soon as Prihanoff had fully matured, both Noble dragon clan and Destructive dragon clan attempted to make him join their clan. However, Prihanoff chose to be neutral and moved his habitat to the barren at the end of this scroll. He said to his best friend and lover Iskog (male Ice dragon) that in his eyes, both Noble dragons and Destructive dragons are the same bunches that crave for power, are manipulative and disguise as protagonist.

Both clans were very upset about his attitude nevertheless, dared to attack Prihanoff, who's one of powerful warriors.

Prihanoff is a fair minded dragon, while he is also quite short tempered.

He left Iskog when he is fully matured because, although he loves Iskog greatly, he also thought Iskog needs an opportunity to meet other partners. In fact, they've been together ever since they were born. For that reason, Prihanoff has been concerned that whether he's been preventing Iskog from having new lover.
