A Box with a Surprise

Exploration Stage: Climate Center
From: January
Description: I was searching for December’s weather forecast when I noticed a strange box on the cupboard I’d never seen before. Could it hold a clue to Christian’s fate? Think you can get it down?
Completed: Inside the box were stacks of signed Christmas cards. That’s just like Christian to be prepared so far in advance. But why didn’t he send them? I hope he’s alright.
