If you have the Dyrisa Castle product, you may have noticed a large building about which the notes say "A temple of the Order of Hyvrik. Since its completion in 715, the archbishop spends much of his time here."
Do you want to know more? Then have a look at this - because you get a full and detailed history of the temple along with floorplans describing every last inch of the place AND notes on the main priests who work here.
Now should your adventures lead the characters to Dyrisa, they will be able to visit the temple and meet the resident clerics, consult the library (if they can gain permission!) or attend worship in the Hall of Ritual.
If you are at a loss as to what to do here, several adventure hooks are provided. However, it is a delightful reminder of how everyday life goes on everywhere in Hârn no matter what the party may be up to... and is a fine example of how to detail one establishment within your world.
