Darwath is the setting of a series of fantasy novels by Barbara Hambly, initially a trilogy in the 1980s, followed by various later sequels.
- The Darwath trilogy — The Time of the Dark, The Walls of Air, and The Armies of Daylight — tells the story of Gil and Rudy, two ordinary Californians who are recruited by the wizard Ingold Inglorion to help save his world from the Dark.
- Mother Of Winter — Ancient aliens are terraforming the world back into its ancient form, with only Ingold and Gil to stop them, while Rudy uncovers the origin of the Keep's power.
- Icefalcon's Quest — The Icefalcon must return to his roots to rescue Prince Tir.
This series contains examples of:
- Comic-Book Fantasy Casting: Ingold Inglorion is very obviously the late Sir Alec Guinness as Obi-Wan Kenobi, brown robes, beautiful voice and all.
- Corrupt Church: Darwath has a generic "The Church" that frequently makes Our Heroes miserable, having as a central tenet of its faith that wizards are evil and soulless. It also generates some interesting Church vs. State conflicts regarding food distribution and legal jurisdiction, wrangles between two bishops — the compassionate Maia of Thran (an ex-soldier) and the fierce ascetic Govannin Narmenlion, who is less 'corrupt' than utterly convinced of the rightness of her beliefs — and is, on occasion, somewhat helpful by providing historical records.
- Crapsack World: Darwath is being invaded by flesh-eating Lovecraftian monsters, but that's just their top problem; also, their world is sliding into an Ice Age, and the Church is zealously destroying the wizards and magic-tech that are the only things that just might save them.
- Cthulhu Mythos: While never named, the Mother of Winter is clearly Shub-Niggurath from H. P. Lovecraft.
- Data Crystal: The earlier human civilization that built the Keep of Dare used magitech data crystals to store information.
- Expecting Someone Taller: In The Time of the Dark, when Rudy sees a young woman being given lots of bossy instructions when she takes the baby heir to the throne out for a bit of air, Rudy assumes the girl is the most junior nursemaid. She's the Queen.
- Extradimensional Power Source: In Mother Of Winter, Rudy uses 1-dimensional strings to gather preservation magic, a 2-dimensional circle to summon animals, and a 3-dimensional sphere to summon water and rehydrate potatoes. The secret to using magic from 4-dimensional objects is passed down to Ingold for the finale.
- Functional Magic: Mages possess an inherent gift, which must then be developed with training in Rule Magic.
- I Choose to Stay: Both Gil and Rudy have found reasons to stay in Darwath by the end of the trilogy.
- Retcon: The 5th book just casually mentions that there's been disembodied 'demons' everywhere, all throughout the series. Everyone just ignores them, so thoroughly that they were never mentioned. The only reference is an occasionally mentioned 'demon-catcher', sounding similar to an American Indian dream-catcher in our world.
- Single Precept Religion: "The Church" has no visible theology other than "wizards are evil", no connection with the real life of the people, and no discernible purpose beyond making people, and especially Our Heroes, miserable.
- Trapped in Another World: Gil and Rudy. It's not that Ingold can't take Gil and Rudy back to Earth, but if they don't deal with the Dark first there's the risk of the Dark learning how it's done and coming to eat Earth.
