Includes both new books > over 300 pages of content > plus the Devil Issue of Gary's Appendix, filled with articles by a collection of OSE/OSR designers.

150+ pages largely composed of three sections: a host of new spells and creatures, everything you need to flood your world with all manner of cults, plus a 3-adventure storyline that begins with an investigation into a newly discovered crypt that's spewing putrid water and ends with a climactic and desperate battle beneath a wizard's tower!

150+ pages of a larger, varied adventure path. Four adventures take the party from the Material world and into the core of the Lesser Planes. Crawl across malicious hexes, slip through monochromatic dungeons, and take part in a hellacious heist set smack dab in the middle of an infernal city!

At 48 pages, Issue 10 plunges into the lower planes with a full lineup of demonic content: summoning rules, infernal contracts, loathsome lairs, and fiends that corrupt from the inside out. Six articles by five established authors.
