Sister Sasha was not a dance partner of the Eternal Self, but rather a nun of "The Banqueter."
The Banqueter was one of the very few Angel Envoys, dance partners, lovers, and followers of the Eternal Self.
He was neither human nor elf, but a dragon.
Tracing back to their roots, all blood of the Children of the Moon originated from The Banqueter, and for this reason they were also known as the Children of the Dragon, granted with the traits of immortality and the ability to grow by consuming Phantom Demons.
And Sister Sasha was the mother of the first Child of the Moon.
She was a servant who served The Banqueter, and at the same time, his lover.
She received the blessing of the Eternal Self and gave birth to the first Child of the Moon who had both dragon's and god's blood — not transformed after death, but born a Child of the Moon from the start.
