[Question] [ Imagine a city full of people that are immortal; they can't die by aging and normal weapons can't hurt or kill them. So the government needs to find ways to overcome its overpopulation issues. After a protest of their previous attempts to handle the situation by execution, they were executed by weapons w...
[Question] [ There is an underground vault containing something very valuable. To prevent robbers from tunnelling to it, the security personnel regularly scans the ground with sound and geophysic sensors. Some robbers are aware of it, but they want to build a tunnel anyway.

[Question] [ I'm attempting to design a desert area that could almost constantly be covered in a thin layer of smoke. It does not block out the sun but instead sticks closer to the ground.

[Question] [ My main character is based on the basic concept of a vampire. That she needs blood to survive. She was genetically engineered to digest ‘blood’ instead of eating. She still needs to drink water. Where she varies from a vampire is that it isn’t real blood, it just mimics the idea of it, so it’s basically ...
[Question] [ I recently started to wonder how an animal could evolve a gun. So I decided that here was the best place to find people that are smarter and/or have different ideas than me. * This creature has an endoskeleton, about 1ft (30cm)tall, 1ft (30cm)wide, and 3ft (1m)long without the neck. * Its neck is 1ft(30c...

[Question] [ The world I'm building is similar to medieval Europe but with magic and dragons. Instead of riding horses knights ride dragons.

[Question] [ There are some pieces of media in which a city borders a wasteland that remains after nuclear apocalypses.

[Question] [ The abovementioned fictional race aren't exactly merpeople from fantasy, but I call them like that just for the sake of convenience.

[Question] [ In a science-fiction story that I am writing, there is a species of bears that only live in a specific oceanic island.

[Question] [ I'm thinking about a species that is at the intelligence level of proto-humans. They have limited language but can still discuss concrete things with a little bit of abstraction.

[Question] [ In my science fiction story,there is a phenomenon happening on the moon that looks like a red mist (or nebula, if you will).

[Question] [ I'm making a fantasy world and wanted to incorporate curses and geases into the story. When I say "curses" I mean two types, but mainly this: ![Greek Curse Tablet](https://i.stack.imgur.com/CElEM.jpg) The type where you write your curse and either: perform a ritual, break it, or maybe bury it.

[Question] [ Many fictional worlds have their civilizations (usually the bad guys) ride some sort of carnivorous animal, usually something like a wolf or a creodont.

[Question] [ In my novel, I was planning to have the palace/citadel type place located inside a mountain- so like a sort of cave type thing, but on a bigger scale.

[Question] [ Many other questions, as well as a few online sources, all agree that in order for me to have multiple sapient species in my world, they need to be either separated by a natural landscape or not a source of competition to each other. The easier solution here is to just set up a natural barrier in between...
[Question] [ Okay, so its been said by various people time and time again that overtly huge fantasy melee weapons are not practical in any way whatsoever. They are too large and cumbersome, and in a fair fight against anyone else wielding a more sanely-sized weapon, the guy with the overtly large weapon would lose. H...
[Question] [ When we consider what alien life might look like, it seems more likely that life would be, well, very alien. There is no reason to expect bipedal, human-shaped and human-sized creatures. Or to expect these creatures to live on the same pace and time scales as we live, there is even less reason to imagine...
[Question] [ So, I have been trying to come up with ideas for space launch without rockets for this sci-if project, but then something occurred to me: rather than have craft jumping off and onto a planet’s surface, why not have them remain in orbit and instead have the *occupants* go up and down? Here’s the idea: the...
[Question] [ Humans and elves have a common ancestry, and are genetically similar enough that they can interbreed.
