Why didn't Shojo just send his wizard to fetch the order?

Or if you want to read the entire plot arc about all of them playing dwarf clerics through that fictional module, it starts here.

(Though fairness requires me to note that it would seem at least slightly less powerful had the author not misremembered how Weapon Familiarity works--probably because the dwarf he talks about being in his actual D&D campaign was a fighter/ranger/Dwarven Defender, not a class without martial weapon proficiency.)

For fun once I made a party of all clerics, who used clerics flexibility to cover archetypes of other classes. Its gets more crazy in pathfinder, where you have optional archetypes.
