Cosmic Nights

Appearance
A rather small pair of claws that glow with a strange purple energy. They have a design that is obviously inspired by galaxies (or the dark matter camo from Call of Duty Black Ops 3 but that's beside the point). However before Izuna released her energy in front of some of the traveller's of TTN they were a rather plain grayish colour but they still glowed purple.

Wielding the weapon
The weapon is incredibly hard to wield due it's small size as it is specifically designed for the smaller Izuna and balanced for her very fast paced fighting style. That's not even to mention that her very soul is in that weapon and it will refuse to be wielded by anyone else. However when she wields it the weapon freezes itself to her so it doesn't come off in combat and when it does it feels and acts like part of her body.

Making the weapon
The weapon is made of Norn stone which is incredibly durable. It's usually found underground in Heia which is why it's so expensive as scrap. And since most Heians die due to how ridiculously cold it is underground before they find it. And that is the easy bit. Getting your soul into it requires you to do something horrible betrayal and murder are usually enough. And since your soul is in it can be called a Blastia.
