Unredact Threatening Document
Un-redact that thing!
The instructions from the badge:
Someone sent a threatening letter to Elf University. What is the first word in ALL CAPS in the subject line of the letter? Please find the letter in the Quad.
Much like finding the Turtle Doves, there is not much else to do but to explore the environment with careful attention to details, such as documents lying around … until you find it:

When you click the piece of paper in the corner, you will be redirected to an URL which loads a PDF document with some redacted parts.

In order to read the redacted part, simply hit Ctrl+A or use the mouse to select all text, and copy paste it into some empty text editor, to reveal the full, un-redacted contents.

To the Administration, Faculty, and Staff of Elf University
17 Christmas Tree Lane
North Pole
From: A Concerned and Aggrieved Character
Subject: DEMAND: Spread Holiday Cheer to Other Holidays and Mythical Characters… OR
ELSE!
Attention All Elf University Personnel,
It remains a constant source of frustration that Elf University and the entire operation at the
North Pole focuses exclusively on Mr. S. Claus and his year-end holiday spree. We URGE
you to consider lending your considerable resources and expertise in providing merriment,
cheer, toys, candy, and much more to other holidays year-round, as well as to other mythical
characters.
For centuries, we have expressed our frustration at your lack of willingness to spread your
cheer beyond the inaptly-called “Holiday Season.” There are many other perfectly fine
holidays and mythical characters that need your direct support year-round.
If you do not accede to our demands, we will be forced to take matters into our own hands.
We do not make this threat lightly. You have less than six months to act demonstrably.
Sincerely,
--A Concerned and Aggrieved Character
Confidential
