I have been tossing with this idea for one of my players but i would like to have you opinions on this.

The PC (a low level priest of sera) want to establish a temple holding in the province of lemnjohen of the giantdowns.
He is secretly contacted by a group called "the white hand". What he doesnt know is that the group is in fact from the kriesha temples of the white witch, trying to infiltrate in the human provinces of the giantdowns.

The group gives the priest of sera all kinds of financial support to establish the temple, and sometimes ask a favor in return. The name of the temple is "Circle of the white coin".

Since kriesha's portfolio is also wealth,making money and trade, it seems to the pc that he has a temple of sera.

my question to you all, how would you handle such a situation? that the temple of sera is in fact a temple of kriesha without letting the PC know about it. how would you cover it up?
