It doesn't look like much to modern people, but during the Iron Age the hill fort is a great display of a ruler's wealth and power. A hall sits on the top of the hill protected by an inner wall. The wall has been constructed from a shingle beach and has partially collapsed over time.
The inhabitants of the hill fort have paved a trail through the old forest leaving lots of tree stumps. I will be working for a while if I want the scene to look like primeval forest. Ancient boreal woodlands are dense and rich in color from biological diversity. There has to be a mixed age-range among the trees, many standing dead trees, a decaying ground layer of debris, lichens, fungi, and mosses. An ancient forest will have lots of character, gnarly trees come in all kinds of shapes, some will be charred from fires, and signs have been made by generations of animals.
