Star Singer

The Star Singer (星詠) is the official title given to the Reyvateil that sings EXEC_CHRONICLE=KEY/., and whose life was created and raised for that specific purpose. It's officially known that this also was a ceremonial title among the Teru that live in Sol Ciel, but unfortunately, there's no information at the moment about what role the Star Singer had among the Teru before Chronicle Key's creation.

The role of the Star Singer is basically to shut herself inside the Crescent Chronicle, and continue singing Chronicle Key without any pause to keep active the seal that maintains Mir sleeping. This has to be done continuously for at least twelve hours in order for the seal to be at maximum strength at all times, since otherwise, the strength of the seal would weaken, and gradually allow Mir to fight against it.

The Star Singers are invariably Pureblooded β-type Reyvateils, due to having anatomical and strength specifications that Third Generations can't reach. They are created in the city of Platina, raised under a rigorous training regime to bring out the power of their songs, and taught all sorts of things about the functioning of the Tower and other matters. Then, when they turn eight years old (two mere years after their birth) they are sent to the Tail of Reminiscence in company of the general populace of Platina and Em Pheyna to undego a ceremony that will bestow upon them the title of Star Singer. Then, they are sent to Em Pheyna and the Crescent Chronicle, upon which they must start singing.

However, and unlike what Misha has led us to believe, Star Singers only must sing for around 30 years. Once this time expires, they will be released from their responsibilities, and will be allowed to live however they wish in the city of Platina, while receiving full support from the government. However, a little before that time, a new Star Singer will be created and trained to replace her, thus reinitiating the cycle. This measure was put in place because some of the first Star Singers got killed in accidents, and because the power they exhibit when singing Chronicle Key begins decaying after that span of time, so in order to keep Mir's seal functional, the singer has to be replaced.

Currently, the only known Star Singers are Misha Arsellec Lune, and the founder of the Star Singer lineage, Lune. Tastiella de Lu also was known as an Star Singer when she was alive, but given she wasn't a Reyvateil, and she gave her life to create the Crescent Chronicle, the definition given in this article can't be applied to her.
