1. A fantasy in which no animal is the same as on Earth, but nor are they simply replacements with different names and designs.
2. A theology-focused fantasy in which the characters do logical debate about God and gods. By logical, I mean make all sides logical, not just the one you think is right.
3. A healing system where healing is possible, but the injury or sickness healed would be imposed on the healer forever. Bonus points: don’t make this one dark and depressing.
4. A fantasy world without humans. Bonus points if they’re not all furries.
5. A fantasy in which there are tens of contradicting and intertwining prophecies and no one knows which ones to believe.
6. A world where every aspect of the environment is different. For example, two blue suns rather than one yellow one, sentient plants, currency-growing trees, trees that grow downward.
7. A technologically-advanced society living literally on top of a medieval one, and a valid justification for why the medieval one doesn’t shape up and get techy.
8. The protagonist being a researcher or engineer whose conflict comes from which side of a war or political spectrum to give his creations first.
9. The protagonist being the world’s god. Making him or her interesting goes without saying.
10. A guard protagonist. Bonus points if this guard doesn’t end up joining some sort of rebellion and traveling the world in search of a McGuffin to destroy the Evil Overlord.
11. The Evil Overlord as a protagonist. Bonus points if his actions are justified enough to make him just as “good” as the rebels.

13. A protagonist who is not interested in romance to begin with and is still uninterested in the end.

15. A world made of water, water-faring races, and nothing else.

26. A world in which magic was so powerful that it created an apocalypse, and now your protagonist is living in a non sci-fi post apocalypse.
27. A seafaring fantasy where your protagonist is not a pirate. Bonus points if s/he’s not in the navy, either.

29. A fantasy where research has advanced differently and computers exist, but not guns or much of anything else.
30. An astrology-based fantasy where astrology does not just mean star-based magic. Maybe your people have just discovered that their world is round.

32. A fantasy world that has developed electricity.
33. A gray versus gray war. No evil overlord. No chosen hero.

38. A magic system where anything written in red ink becomes true. Bonus points if this magic is commonplace and the world isn’t destroyed.

41. Write a fantasy comedy that doesn’t rely on English wordplays and puns. Bonus points if it’s actually funny.

43. The evil overlord does the intelligent thing and kills the hero as a baby. Now what?

60. Technically a sci-fi, but future sentient races have created a world where fantasy conditions exist. Dragons, magic, evil overlords, and everything. Pick and choose, though.

70. A religion or race that considers speaking profane and thinks mouths are only there for eating. Hint: study sign language.

73. Your protagonist doesn’t get stronger with every battle, but weaker as his or her injuries pile up.
74. A magic system based on emotions, where an angry mob could set fire to a stick by looking at it or something like that. Catch: no one person could change much of anything.
75. A world shattered by earthquakes and a sentient race adapted to it. People would be really good at jumping, I think.
76. A fantasy where the world actually is flat, or at least a cube instead of a sphere. Bonus points if you can come up with a feasible reason for it.
77. A world where the primary race is mini-sized and insects are an actual difficult battle. Cats, dogs, horses, and elephants would be monstrous.
78. A world without magic suddenly gets magic.
79. A world with magic suddenly loses its magic.
80. The protagonist is an engineer. Yes, I’m still giving fantasy prompts. And yes, engineers should still exist in fantasy. They’re just people who use science to solve problems.
81. Death makes people into zombies of sorts who age backward, and once they’re infants again, they become human again and start aging normally.
82. Every fifty years, the magic system changes.
83. Every fifty years, a new sentient race is created.

88. A world where structures are built out of a material not found on Earth.
89. Structures on land are built using water.
90. A world of all men or all women, with no apparent means of reproduction. Bonus points if they can save themselves without blending into sci-fi or using deus ex machina.
91. A society where people don’t have names. Bonus points if you don’t take the obvious route of making it a pseudo-communist individualism-hating thing.
92. A world where raw ideas are actually worth something–where the people generally act on their ideas, and where ideas can literally be stolen from people’s heads.
93. A world where the god or gods made a mistake in their creation. What that mistake is and what it does, I’ll leave up to you.
94. Write about the very beginning of your fantasy world. Bonus points if you don’t infodump. Extra bonus points if you don’t just re-write Genesis.

98. People are walking bombs, and when their hearts stop, they explode.
99. Everyone in the world operates with a different magic system.
100. Go ahead and write 100 of your own ideas/prompts. This will help you get your creative gears going, as you’ll inevitably think in some depth about each item.
That was fun. I think I’ll do it again sometime.
