Possibly the coolest low-level modules I've read. The Dungeon Crawl Classics RPG has each player create a few 0-level PCs a piece and the few characters that survive the first module become classed characters; 'Starless Sea' really captures that desperation, with a mob of villagers besieging a ruinous keep purely to prevent its inhabitants from further preying upon their families. There are no heroes in town--the villagers must make due themselves. And by the end of the module, after losing a few peasants in striking and memorable ways, each player may be lucky enough to emerge with true hero to call his own.
The opponents and the general feel of the module is VERY Appendix N / Michael Moorcock / Warhammer Chaos / Lovecraft. The enemy has its own motiviations and is working towards certain goals, so if the peasants fail, the world will be worse off for it. 'Starless' is a dungeon crawl, and for those who are quick to dismiss crawls as boring or too straightforward (which was me until recently!), it's great to see how such a relatively simple RPG style can have so much depth and flavor. 'Starless' is no railroad, either: the players can approach the problems at the keep in whichever way they can imagine. The module rewards clever decisions and otherwise chews through peasants without mercy.
The writing and layout are excellent, and the artwork really captures the mood and excitement of the story. Would, I'd imagine, convert with relative ease to other systems.
[5 of 5 Stars!]
