New Capenna

New Capenna is a city of steel and chrome that rises from a plateau of vast emptiness and long-abandoned townships, a testament to the might of its long-forgotten founders. The city is surrounded by a skirt of wires and a shield of diffuse Halo, the very essence of the angels. This barrier that the builders had left behind remains, a last bastion of hope against a great, now forgotten evil. Outside the city, the plane is desolate and devoid of life.   The city is encased in a dome that keeps it consistently temperate. Though it has a government, it is so ineffectual that many don't even remember its name even after decades of life on the city. Rather, the monopoly on violence within the city is wielded by its five ruling families.   New Capenna is reliant on Halo, with myriad uses including as a healing elixir, for teleportation, and to enhance spells. Its importance to the city's society has caused it to be used almost as currency, and shortages are a cause of citywide tensions. Nido Sanctuary's vault is said to keep a so-called "Doomsday Prophecy" foretelling the city's destruction when its supply of Halo runs out.
