Cipher Drop: The Feather Mark

When words are illegal, we let letters wear masks. The Feather Mark is a simple swap—easy to teach, fast to pass in a crowd. We carve it into bread crusts, stitch it into cuffs, chalk it where rain can argue with it by morning. A child once solved it faster than a captain; both were recruited. Today’s drop hides a meeting place and a warning. Decode it, carry it, then scuff your footprints on the way out.

How to play: Use the included key. We’ll post the solution two weeks from now in the comments.
