Planes of Monvesia: Dominions, Part 2

In the cosmology of Monvesia, demi-planes are called Dominions.  These are further divided into Greater Dominions and Lesser Dominions.  The former include the Thrones, which unite the Comic Marches with the Elemental Planes ans serve as home to aeons, angels, and archsaints; also the Powers, which unite the Mortal Realm with the Otherworlds and are home to particular otherworldly mortal races. Principalities are the lowest class of the Greater Dominions; these unite the Otherworlds with the Cosmic Marches, and serve as home to the immortal archdaemons.

The Lesser Dominions are all other demi-planes, great or small.  Though never as large as a Power or Throne, many lesser dominions do rival the Principalities in size.

Principalities

The Principalities are shared by an Otherworld and three Cosmic Marches.  Each Comic March contains two principalities; while each Otherworld contains only one--therefore, their are eight Principalities.  These are the domains of the archdaemons--transcendent immortals of the otherworlds.

Mortals know very little about these planes--for few have conceived that they might exist, and even fewer have had the chance to visit them.  While not visible from the Mortal Realm by mundane means, they could be perceived through the use of extremely complex astrological equipment.  If detected, they would be seen as companions of the Powers.
