Nidhogg is Leonora Lancaster's contracted spirit.
It is a military elemental spirit in the form of a dragon.
In elemental waffe form, it transforms into a large sword known as «Dragon Slayer».
- Dragon spirits' specialties were their overwhelming strength and their high resistance against magical attacks.
- Especially with their «Anti-magic Dragon Scales» on, their magical resistance against the five main elements multiplied.
- It is named after the Nidhogg from Norse Mythology, much like Fenrir. Nidhogg is one of the several giant horrors of the mythology, specifically, it is an enormous dragon who chews at the roots of Yggdrasil, the world tree itself, devouring the souls of the unworthy dead of Nastrond, the worst pit of Hel where those guilty of the worst kinds of crimes were inevitably sent. To be devoured by this dragon was considered a horrible fate, even compared to ending up in Hel's realm in the first place.
