Are there holy sites?

[Corinthian]

Interestingly enough, there is actually a level 4 Holy site that you will never find. As I recall it is rather terrible though. Have only seen it in the wiki.

Personally I suspect that if you take the number of holy sites + number of astral sites = the average number of elemental sites. So if you are interested in astral pearls for some unknown reason, it could be a good idea to send a lvl 2 priest to look around a bit.
