Arcadia thrives with orchards of perfectly lined trees, ruler-straight streams, orderly fields, immaculate roads, and cities laid out in geometrically pleasing shapes. The mountains bear no trace of erosion.
Night and day are determined by an orb that floats in the sky above both of Arcadia’s layers. Half of the orb radiates sunlight and brings about the day; the other half sheds moonlight and brings on the starry night. The orb rotates evenly without fail, spreading day and night across the entire plane.
The weather in Arcadia is governed by four allied demigods called the Storm Kings: the Cloud King, the Wind Queen, the Lightning King, and the Rain Queen. Each one lives in a castle surrounded by the type of weather that ruler controls.
Arcadia is suffused with a vigorous life energy that bestows great vitality on visitors (see “Environmental Effects” in chapter 3).
Everything on Arcadia works toward the common good and a flawless existence. Here, purity is eternal, and nothing intrudes on harmony. Individuality is subsumed to peaceful life in community, and military might can be brought to bear on those who disrupt that peace.
An adventure in Arcadia can be an opportunity to explore the tension between individual freedom and societal responsibility for the common good. Even lawfully inclined adventurers rarely conform neatly to social expectations, and a visit to this plane can highlight that conflict.
