Newbish question

[Endoperez]

It is a Holy spell, so your priests can cast it. If you haven't appointed a prophet yet, you can make one and he will become a priest. If your prophet has died, you have to wait six months before you can appoint another.

You can also recruit priests from provinces where they are available and which have a temple. Any province you have forts in, including your capital, has priests among the commanders, and priests are common among independents as well.
