Great Forest of Sildanyr
The great primal forests of Sildanyr remain unseen by human eyes. This massive expanse of trees, largely unchanged since the days the great glaciers first receded from the face of the world, stretches for more than a thousand miles, practically a full quarter of Ilia. Those who dwell within are otherworldly—wilden and sprites and fey that, despite their centuries of habitation, are still strangers to the world of Ilia. Within Sildanyr are living things, tree and tree-dweller both, that can still remember the birth of their race in the world.
Sildanyr itself is an enormous stretch of mostly temperate forest. The majority of the trees are towering, broad-leafed deciduous growths. Oak and ash trees are the most common, though Sildanyr also boasts beech, chestnut, and other varieties so ancient and deep in the forest that no human has a name for them. Many of the trees of Sildanyr are mightier than their cousins elsewhere in the world. The mightiest oaks tower hundreds of feet above the forest floor, their trunks wider around than many city towers. The forest canopy is practically a sky unto itself, and even the lower levels of the underbrush are often tall enough for a full-grown man to step into and disappear. On the eastern coast, the oak and beech are replaced by an unusual mixture of cedar and redwood near the mountains and pines with an underlayer of ferns nearer the sea.
