No processo de tentar conectar-se ao Huldra sendo às vezes referenciado como tendo caudas de vaca e, portanto, sendo o primeiro referência, eu também achei outra página (aviso justo, foto levemente saucy) que respondeu à minha pergunta que eles são de fato a mesma criatura sendo referenciada para ambas as partes da consulta.
Huldras are extremely beautiful from the front, but from the back they have a cow’s tail and a hollow back “like an old tree trunk”. In some stories, if you saw the back, her spell would be broken and she would turn out to be horribly ugly.
Então, a pergunta foi respondida, mas achei que iria em frente e compartilharia. Aliás, a referência mitológica é relevante.
The one known as Dire is actually a digital intelligence that originated in a future where digital intelligences in charge of waging war got too good at their jobs and realized that they needed to change the past to ensure that humanity would survive. The body is merely a hollow biological shell in which the digital intelligence orb resides.
