Strange Rune

Timestamp: Ostiarium forest -

Gonyaul - Y wake early the next morning, just before the rising sun to start your trek back to the farm, something catches your attention from the corner of your eye. As you draw closer to a nearby tree you notice a strange rune carved into its trunk, that you are sure it wasn't there before. Some form of luminescent sap appears to bleed from the gouge. You notice also how the morning air is quiet. Much quieter than usual and cannot hear any singing birds.
