Exarch

Exarchs are divine beings of extraordinary power.

Exarchs are often called demigods (but note that exarchs are not gods (as in Demigods) of demipower status (despite the name)) or heroes. Many are ascended mortal servants of greater gods, brought up from the world to serve as agents of their divine masters. Many, but not all, attract worshipers of their own, and they have some ability to grant spells, but are more often simply conduits from the mortal world to the attention of the higher gods.

The divine hierarchy of a deity has exarchs at the top, just under the deity, and other divine servitors under them (known as proxies in older editions)

A Chosen is not the same as an exarch, though it is possible for a Chosen to ascend to the rank of exarch.

For example, the druids of Gulthandor pay homage to the Lion God, but in reality the character's divine spells are being granted by Nobanion's patron, Silvanus. Unlike true deities, exarchs are not bound to live in Astral Dominions with their patrons. Like Nobanion, many choose to live on the Material Plane, more directly engaged in the lives of their mortal followers.
