The Transmigragem is a gem first mentioned in BF6 of Yggdra Union that allowed the Undine race to survive as a species through reincarnation. Nietzsche's unnamed sister stole the gem for a mysterious lover; the man took the gem and left her, breaking her heart in doing so. As a result, the unfortunate girl took her own life as the entire Sovereignty of Embelia was thrown into turmoil and unrest. The actions of her sister also condemned Nietzsche to the point where she was forced out of her country.
