In the
AD&D Planescape setting, the
Outer Plane otherwise known as the
Seven Heavens. The plane of pure
Lawful Good, it is divided into
seven layers, depicted as ascending levels on an infinite mountain. The names of the layers are taken from the planets of the
Ptolemaic system, after
Dante's use of those
planets for his vision of
heaven in
Paradiso.
Lunia: The heaven of
the Moon.
Mercuria: The heaven of
Mercury.
Venya: The heaven of
Venus.
Solania: The heaven of
the Sun.
Mertion: The heaven of
Mars.
Jovar: The heaven of
Jupiter.
Chronias: The unreachable heaven of
Saturn.
Jovar is dominated by the
city of
Yetsirah, which obviously owes its imagery to the theme of the
New Jerusalem in
Christianity. Chronias is approached through the city, but none have ever returned, save the
archon or
angel who rules that place.
