Frozen cold air

Exploration Stage: Christmas Headquarters
From: Miss Izzy
Description: As the new Santa, it is my duty to regain the trust of the elves. The elven glassmakers pride themselves on their ability to melt even the most ancient ice. To show my appreciation, I need some Lapland glass, and I need you to find it for me.
Completed: Did you find the glass in Lapland? I don't know how to thank you! This isn't real glass, it's dragon's breath that has been frozen in place for thousands of years. I'm sure the elven glassmakers will come back to us when we present them with this material!
