Devotion to the Cause

From: Miss Izzy
Description: How is Santa’s title transferred? It’s simple. The retiring Santa draws up an order and passes it to his successor along with his badge. I brought a safe with these documents, but the lock on it has frozen solid. Please bring me some artifacts that can melt the ice!
Completed: Great, the ice on the lock melted, and I opened the safe! I should submit a proposal to finalize its design. I have no idea why no one had thought of the fact that the lock could freeze... Anyway, let’s get back to the papers!
