Krinir ore

Krinir ore from the Spyral mines.

"People ask us all the time about where our wealth comes from. Well, it's right here, in Krinir. As light as a feather and as hard as a dragon's hide."
―Ryden Spyre, to Euron Greyjoy
Krinir is a precious Silvery metal, very lightweight but capable of providing extreme strengths in alloys, which was mined by the Spyres in the deep mines of Spyral. Krinir is also extremely easy to craft because of it's light weights.
