Hoshi no Musaboru

Hoshi no Musaboru, was an eldritch power at the heart of Nazo Mori, an entity of unknown origin which eventually took an Ishiken, Hasana, as its herald, and she called it the Eater of Stars or simply, “the Master.” Hasana swore to serve it so long as she could still speak to her deceased twin brother Haruko. Taking the name of Tsunagari, she committed terrible actions and atrocities in service to her Master and considered herself to be his herald, the Voice of the Stars. Tsunagari managed to invade the minds of other people merging her own unstable grasp of Void magic and the influence of the cursed Kaidanshu Whispers of the Stars, until a group of samurai managed to defeat her.
