White Dragons are pacifists and specialize in extremely strong healing magic. The only limit of this magic is that it can’t bring back the dead. They only eat plants and never kill living things.

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.

Euterpe is IFNT pact's muse. She is the female dragon that inspires all IFNT for anything they see or believe as artistic and thoughtful. She usually hangs with the IFNT pact, singing soft songs along with them, or flies around with Emilia.

It seems that Euterpe spends most of her time pregnant after mating with IFNT pact members. (They claim that without Euterpe, they cannot think.) Because of this, other female dragons disregard Euterpe as flighty and amoral. However, it seems that her close relationship with IFNT is not the only reason behind the jealousy.

Euterpe comes from a long line of royal heritage. She was praised as a goddess-like dragon before joining the Kriss tribe. The only reason why she gave up all her fine name and royal heritage was because she fell in love with Rainwize, who whispered soft musical hums.

It looks as if Euterpe is very talented at everything and loved by males. Because of this, despite her kind heart, she is always envied and hated by females.
