An RPG Resource Review:
The Temple is to be found in the Great City in the Temple Ward (although of course you can put it anywhere else that suits). In this product, you get a fully-detailed plan of the Temple including the NPCs to be found there and ideas for things that might be going on. The plans, of course, take advantage of 0one Games's mastery of PDF technology; you can configure them to your heart's content to make player and DM maps and there is even a three-dimensional view to enable you - and the players if you want to show them - how the whole thing hangs together.
But it's not just a location... there's plenty of background information to enable the religion of the Silver Lady to come to life in your campaign world. There are even rumours which characters can gather if they are curious about the Temple or the faith practised there. The first trick is to get in: there are no obvious entrances into the shiny dome that is the outer face of the Temple.
As well as all the detail about the various people to be found in the Temple - and they are a well-crafted bunch who you can imagine getting on with worship and the rest of their lives whether or not there are any player-characters around to see them - there is material on the faith itself and the specific clerical powers it confers. There's also a prestige class, Moon Warrior or Warrior of the Silver Lady, for religiously-inclined fighters who wish to dedicate their lives to service of the Silver Lady without laying down their arms.
Overall, it is well thought out and provides a slight air of mystery for low-level characters to investigate while avoiding the usual cliches of evil temples to destroy or corrupt priests to unmask.
