James Jacobs was already associate editor on Paizo's run of Dragon
Magazine when he contributed to Wizards' free “Original Adventures” series for D&D 3.5. I understand that he's gone on to
play a more prominent role in Paizo's “Adventure Path”
development, so it was with no small amount of interest that I
cracked open Frozen Whispers. Although this module showcases material from
outside of the core books, the module does not require anything more
than the Player's Handbook, Dungeon Master's Guide, and Monster
Manual to run. Although here is a rules clash between what is
presented in Frozen Whispers and the Pathfinder game, I don't think
it poses a serious conversion problem. Frozen Whispers is not currently available for purchase.
