I found this from the circle. Call me a fool, but I believe this is for you.
Opening the piece of paper you see a crude drawing of a halfling standing over the burnt and charred bodies of four humans in a small chamber. A few goblin corpses also are scattered around the chamber. In a corner is a chest and depicted as floating above it is a jar. The pigment used to color the jar is a dried green goop that glows with its own light. It is splattered roughly over the outline of the jar as if the author took particular care not to touch the goop. Another drawing shows the halfling waiting at the place you recognize as here, the Grey Druid's Circle.
And this one directed me to you
Piece of paper where is a drawing of the halfling from the previous paper handing the jar to a human man in blue, wearing a "stag" helmet and holding a quarterstaff. Looming over them both is a gigantic spider egg.
