Gods and Avatars (GoE)

Gods and mortals exist on different metaphysical levels. A deity and an elf, for example, cannot easily sit down and talk with each other. Creating an Avatar, through the craft action, allows this barrier to be circumvented. It also essentially turns the related god into a foe for use in a campaign setting.
=How Does an Avatar Differ From A God?=
At the most basic level, an avatar is just a form of a god that can interact with mortals. However, more abstractly, an avatar might be a certain aspect of a god that can interact with mortals. For example, an avatar may represent only the part of a god that is kind, or the bestial rage of that god, or something else.
=How Does an Avatar Differ From An Exarch?=
An exarch is an entity fundamentally separate from a god. Like an avatar, it is a mix of the divine and mundane so it can interact both with gods and mortals, but unlike an Avatar, it is not an aspect of a god. This means that an exarch is capable of being more different from its creator-god than an avatar, but it also means that (unless it misrepresents itself), it doesn't interact with mortals as a god.
=Why The Difference?=
The difference between an avatar and an exarch is somewhat subtle. As such, we tend to expect to see far more exarchs than avatars. However, as avatars are unique and do have their purposes, it is useful to keep this distinction.
