This is a system I don't know, and probably won't be playing - I'm not really into "Dark Fantasy" or any of the things they mention in the "if you love xxx you'll love this..." bit, and suspect it isn't really my sort of setting:
"Shadow of the Demon Lord is designer Robert J. Schwalb's dark fantasy RPG of grim heroism against a cosmic destroyer. In this fast-playing, low-prep March 2015 Kickstarter triumph, desperate heroes battle strange magic, unhinged cultists, and roaming mobs of undead while humanity's last great empire slides toward oblivion. Gamers who love Warhammer Fantasy Roleplay, the Ravenloft and Midnight settings, Joe Abercrombie's The First Law novels, or heavy metal music will want this bargain-priced collection of DRM-free .PDF ebooks all about the Void That Hungers.
We provide each ebook complete in .PDF (Portable Document Format). Like all Bundle of Holding titles, these books have NO DRM (Digital Restrictions Management), and our customers are entitled to move them freely among all their ereaders.
Ten percent of each purchase (after gateway fees) goes to this offer's designated charity, the Wildlife Conservation Society.
The total retail value of the titles in this offer at launch is US$98. Customers who pay just US$13.95 get all four titles in our Starter Collection (retail value $44) as DRM-free .PDF ebooks, including the complete 278-page Shadow of the Demon Lord corebook (retail price $20), the Demon Lord's Companion (retail $10), the Uncertain Faith sourcebook of divine magic (retail $12), and the fine introductory adventure Dark Deeds in Last Hope (retail $2).
Those who pay more than the threshold (average) price, which is set at $23.95 to start, also get our entire Bonus Collection with five more titles worth an additional $54. What's in these supplements? The titles speak for themselves: Hunger in the Void (retail $12), Tombs of the Desolation (retail $10), A Glorious Death (retail $10), Terrible Beauty (retail $12), and Exquisite Agony (retail $10). Happy gaming!
At least one more title will be added after launch; "When a title is added after launch, ALL customers who previously purchased the bundle automatically receive the newly added title, REGARDLESS of whether or not they paid more than average. This is their reward for buying early.
