To help balance the four elements, send one or more monks to us to demonstrate airbending, waterbending, earthbending, and firebending over a Zoom video call. (Do not use a real flame without explicit consent from a parent or guardian.) When you're ready, contact HQ (by @ing Linus, Misha, and/or Dan on your team's Slack channel).

Future solvers can reveal the answer below.
