Prophet
A Prophet is a full representative of their 
Pretender God. A common concept west of India in real life, a Prophet is said to relay their god's words to mortal men. They are a crucial figure in many Dominions nations with less-established priesthoods.
Acquiring a Prophet
A Pretender God (a player) may name one Prophet. This is a month-long (a turn-long) process through the "Become Prophet" action; you can have many commanders do this at the same time, but only one will become a Prophet, at random.
If a Prophet dies, that's unfortunate; their Pretender (their owner) must wait half a year (six turns) before a new one may be named. Past that point, the Prophet is no longer considered a Prophet, though they are still considered holy afterwards (if somehow brought back). To be clear, if an Immortal Prophet dies and then comes back within those six turns, they remain a Prophet and a new one may not be named.
In a team game, you don't have Prophets. Instead, you have Disciples, as Jesus did; only, instead of being great holy men, these Disciples are basically weaker Pretender Gods. The design of your Disciples is out of your hands, falling to the other players in your team instead.
Benefits
A Prophet is a selfless fellow, who is incorruptible and requires no Upkeep. Their level as a 
priest becomes 3; or, if it's already 3 or higher, they get a +
1 pathboost. They are always blessed (and sacred), with no need for self-blessing (or blessing from other priests). They also have 30 Morale, preventing them from routing unless things go exceptionally badly. Overall, the 3 is most important, for claiming Thrones.
Prophets are also mobile spreaders of Dominion. This effect is less powerful than what the incarnate forms of Pretender Gods have, but it's just as strong as a Temple. In addition, local Dominion Strength greatly affects their stats, just as it affects Pretender Gods.

If you're lashing out from a province of strong Dominion into one of weaker Dominion, your Prophet's current HP may be higher than their maximum HP. Regeneration won't restore this HP if it's lost, and this HP won't modify your chance of getting Afflictions.
