From publisher blurb:
Designed by Jason Nelson with the Legendary Games design team of Neil Spicer, Greg A. Vaughan, Clinton J. Boomer, Matt Goodall, Jim Groves, Tim Hitchcock, Russ Taylor, and Clark Peterson. Who better to provide you with alternate magical books, spells, and rules for your Adventure Path campaign than the very writers of those adventures themselves? Answer: no one. Legendary Games’ Gothic Grimoires supplement and enrich your campaign experience, offering adventures and supporting products that incorporate and expanding upon unique concepts, themes, and rules subsystems introduced in the Adventure Paths while filling in the background characters, items, and locations that make those adventures come alive in delightful (and often dangerous) detail. Legendary Games combines stellar writing talent with innovative layout and product design, hyperlinked internally and to online Pathfinder resources for easy interactive reference, and top-notch artistic values that we think will bring you back again and again.
