I have decided the message!
I used a Gravity Falls code decoder to figure out the wording, and I got this!
“THIS THING ALL THINGS DEVOURS; BIRDS, BEASTS, TREES, FLOWERS; GNAWS IRON, BITES STEEL; GRINDS HARD STONES TO MEAL; SLAYS KING, RUINS TOWN, AND BEATS MOUNTAIN DOWN. WHAT AM I?”
It’s a riddle, and I think I know the answer.
Time! - Sunrise
