Eberron

Rain never stops falling on Sharn. Down in the City of Towers the lightning rail hums into its berth, everbright lanterns smear the fog, and a soldier home from a war nobody won takes a job he already regrets. This is Eberron — a world where magic never stayed locked in the wizard's tower but went to work: driving elemental airships, binding message-stones, forging thinking soldiers of steel and wood. A hundred-year Last War has just guttered into an uneasy peace, one nation is now a grey and lifeless wound called the Mournland, and twelve dragonmarked houses run the commerce of a continent like guilds that answer to no crown. The shelf is the work of many hands, loosely braided rather than marched in a single line. Keith Baker, who dreamed the setting up, opens it with The Dreaming Dark trilogy (begin at The City of Towers), following a mismatched warband — including Pierce, a warforged construct learning what freedom is for. Around it turn Don Bassingthwaite's The Dragon Below and goblin-empire Legacy of Dhakaan, James Wyatt's Draconic Prophecies, Tim Waggoner's Blade of the Flame, plus noir-tinged mystery and espionage runs — The Inquisitives, Thorn of Breland, Heirs of Ash. Each trilogy is self-contained; the shared spine is the world, not a hero. What sets Eberron apart is its refusal of easy sides. This is pulp adventure — chases, heists, ancient conspiracies of fiends and dragons — told in the register of hardboiled crime, where paladins have debts and villains have reasons, and the honest answer is usually grey. A newcomer should start with Baker's The City of Towers: it is the creator's own tour of the world, and everything else reads better once Sharn is under your boots.
