I know there's been lots of debate on the list about these guys, and
several people have decided that they use variants of druids or shamans for
elvish priests, but in reading through Tuarhievel player's secrets there is
an interesting note on religion. Human religions are outlawed there, but
there is a special provision made that mentions that if an elf chooses to
worship a human deity, that is his choice, he just can't say anything there
at home.

Would this indicate to anyone else that one of the Sidhe could be a priest
in the class sense of the word? It does to me...

Semi-related: What about a druid class that uses the optional
Preserver/Defiler rules out of Chapter 6 in PO: Spells & Magic? any
thoughts?
