Fairy fort / earthen ringfort in Gardenfield

Gardenfield holds a scarped earthen ring forty feet across, old enough to predate human memory in local thought. The soil edge still stands a metre high, marking a circular boundary now choked with abandoned cars and rubbish. What lives inside that ring has stopped being human, or perhaps never was. The fort has become a feeding trough for forgotten things, waiting for the field to empty before it speaks.
