and with a few exceptions, embody one of the five elements: air, earth, fire, water or wood. Elementals are naturally material, requiring charms to dematerialize, and with a few exceptions, cannot reform when slain. Unlike other spirits, their growth is largely unrestricted. The most powerful elementals are the Lesser and Greater Elemental Dragons. Elementals are generally outranked by gods of similar power. While Sorcerers can summon and bind demons through sorcery, the Elementals conjured through a similar spell are brought into being whole-cloth, and frequently cease to exist at the end of their binding. The elementals of Autochthonia embody one of the machine world's elements: crystal, metal, oil, lightning or steam, and cannot be summoned through sorcery. Ghosts The most common type of ghosts, referred to as ghosts or the dead, are the hun or higher souls of mortals who have refused to pass into Lethe and reincarnation due to their attachment to their mortal lives. These ghosts are much weaker than Exalted, and they can only respire Essence in the Underworld and Shadowlands. Hungry ghosts generally come into existence due to betrayal, vengeance or a traumatic death. Initially, a hungry ghost includes both the higher soul and the po, or lower soul, but the hun soon moves on, leaving the hungry ghost largely mindless. Unlike other ghosts, hungry ghosts are naturally material in Creation at night. Nephwracks are ghosts who have been corrupted by the Neverborn.

Spectres, also known as plasmics, are bizarre creatures spawned by the nightmares of the Neverborn. The category of Hekatonkhire includes the ghosts of demons, devas and Primordial behemoths, as well as the manifested nightmares of the Neverborn. The Neverborn are the ghosts of slain Primordials. Immensely powerful, they are difficult to rouse from their slumber, and their power seems largely constrained to the Labyrinth. Only mundane ghosts and Hekatonkhire can be summoned through necromancy, and only mundane ghosts can be summoned through sorcery. Gods Most gods are members of the Celestial Order, which is stratified into two divisions: the Celestial Court, composed of gods of concepts, and the Terrestrial Bureaucracy, made up of the gods of physical objects and locations. Technically, all members of the
