The Orchard

There are many families who can trace their Orchard walks back through generations upon generations. Stop a person on the street, and they'll likely be able to tell you about their great-great-great grandmother's hundredth circuit around the wall. Despite its prevalence in Arvemor, not many facts are known about the Orchard. Fact and fiction have swirled together over centuries of whispered stories, religious texts written with an air of misplaced authority, sparse scientific studies, and hundreds of family testimonies.
Here is what we know. In the center of Arvemor, there is a wall. It encloses hundreds of square miles of land, known as the Orchard. The Orchard is impregnable. No one goes in, and no one comes out. The Orchard is said by some to be the source of all life. Some believe it doesn't exist. Everyone lives in its shadow, and nobody knows anything about it for sure.

Geography

Not much is known about the Orchard. According to The Arborist's Tract, there are fruit trees of every type imaginable, indicating that there is likely fertile soil and an independent water source. No streams or bodies of water are visible coming through the wall. The wall stretches so high into the sky, it blocks out the sun to those who lives around it. The wall is made of wood, although the arborists can never agree on what kind it is. The wall is fireproof, impossible to scar with blades, impossible to batter through. Any method you can think of to break through a wall, the Orchard walkers have tried it.

Fauna & Flora

Birdsong is the only sound that makes its way through or over the walls. Sparrows, jays, larks - mostly songbirds. You'll never hear the harsh caw of a crow or the screech of a raven from within the wall. There may be other animals inside the Orchard, but they are unknown and undocumented.
Fruit trees make up the vast majority of the Orchard's plant life, as far as anyone can know. Once a year, a large crop of apples, oranges, pears, peaches, and many more fruits appear outside the wall. The Gift occurs in a different place every year, and there is no discernible pattern. There may be other plants that thrive within the wall, but there is no evidence of it.
