Obsidian

Magic here keeps its accounts. The High Magick of the Golden City is a discipline of ledgers and ritual — power earned by study, paid for in coin and labor, wielded by Mages who have long forgotten it was ever wild. Beyond the walls, Wild Magic answers only those willing to meet its Price: for every gift, a task set by the world, a debt that must be honored before the spell will hold. And beneath both, patient across a thousand years, wait the Endarkened — demons who do not hunger for conquest so much as for the slow unmaking of everything that loves. The world unfolds across three trilogies from Mercedes Lackey and her collaborator James Mallory. The Obsidian Mountain trilogy opens it — The Outstretched Shadow, To Light a Candle, When Darkness Falls — following the exiled Mageborn son Kellen as the third war between the light and the Endarkened breaks. The Enduring Flame carries the tale a full millennium onward, to heirs who have forgotten the old wars entirely. The Dragon Prophecy — Crown of Vengeance and its sequels — reaches the other way, back to the ancient Elven queens and the first betrayal that set it all in motion. This is high fantasy of the earnest, morally weighted kind: Elves and dragons, unicorns and Knight-Mages, quests where the cost of power is the whole point rather than a footnote. Begin where readers first did, with The Outstretched Shadow, and follow publication order forward. The prequels reward you afterward — they deepen the door rather than open it.
