Acorn Cap

Out on her morning stroll, Fawn noticed a smooth acorn cap sitting on the stump, marking the path towards her home. Upon further inspection, she recognized the tell tale marking of Thorn, one of the Mud Boys. He was ready to show her the flower patch they had spoken of the day before.

Acorn caps are often left in specific orientations and locations, to allow the fae to signal to each other that they wish to meet at some point. This is important because many of them do not have a specific home but stick to a general area.

Mechanics & Inner Workings

Other variants on the standard cap are 'doubles' which have 2 caps attached by a single twig. Doubles can take on additional meaning if one cap is larger than the other, etc.
The acorn caps can also be prickly and rough or scaly and smooth which can also change the meaning to the receiver.

Significance

The fae used to mark their trails and signal each other with the use of acorns but because humans have built in the area, they have had to modify their ways. Using the tops of acorns to signal meetings, is one of the many ways their ancient society has had to adapt to the influx of man.

Rarity

Acorn caps can be found year round as the majority of the land is still covered with forest teeming with oak trees.

Tools

Many caps are used how they are found, however there are times when a message must be delivered along side the meeting request. How and what the fae inscribe can vary.
Some common approaches are to carve divots resembling teeth marks or chipping the edge of the cap to indicate either the time of the meeting or severity of the request.
