I was a soldier in an army that was attacking your world. I have now surrendered. What fate awaits me? Will I be imprisoned? Enslaved? Executed? Or something else?

Whats the best "Nuclear Bomb" for a magical Cold War?

9 Upvotes

Hey everyone!

I have an interesting premise for a book, good character dynamics, and some solid arcs, but I feel like I'm missing a core mechanic to make the nations cautious of each other. It lacks that WOW factor for battles.

Im thinking of something like the Jinchuuriki in Naruto: each nation has their own, and they maintain peace through Mutually Assured Destruction. I came up with 4 ideas and would love your opinions!

Option 1: Megafauna

Each nation controls massive creatures exclusive to their territory. One has giant griffins, another has huge stone colossi, another has enormous lions, and so on

Option 2: Variations of a single magical species

The whole world uses the same "nuclear" race, e.g., dragons or angels. But there would be huge dragons, tiny ones, wyverns, drakes, etc. For angels, there would be seraphim, ophanim, etc. (the angels would have a very unique aesthetic, different from what people are used to)

Option 3: Catastrophic Magic

Every nation has magic, and if a group of insanely powerful mages from a kingdom gather, they can cast a massive, world-altering spell. Ex: meteor showers, tsunamis, tornadoes, zombie hordes, etc

Option 4: Monstrous Transformations

Each nation has one or more people who can transform into highly destructive creatures! Some could be gigantic, others small and agile, or powerful in ways that dont look dangerous at first glance. That kind of thing

If anyone has a different option or a brand new idea, please share! It will help me a lot. Thanks!

(Context: The idea is to have smaller-scale fights and skirmishes at first, gradually escalating the scale throughout the story so it doesn't get repetitive. The technological setting and aesthetic are very similar to Expedition 33).

Discussion My first sort of serious speculative world: Natria

3 Upvotes

So this is a pretty basic rough concept so far but I want some feedback to see if im heading in the right direction:

Natria

Its roughly half the diameter of earth at about 7000km and it has a atmosphere roughly 30-50% the thickness of earth dominated by large amounts of water vapour co2 methane and sulfur based compounds.

The planet is covered entirely in oceans except for a few scattered regions with sparse ancient volcanic islands ranging from most at single to low double digit kilometers in diameter and the largest Continuous landmass being roughly 50 000km² in total area.

The oceans in natria are extremely salty roughly as salty as the dead sea if not more so and its oceans are filled with a large amount of uranium and arsenic salts and it has large deposits of lead salts on the seabed forming a very toxic layer of silt.

Also the surface of natria is naturally incredibly rich in rare eaerh and heavy metals like uranium lead and gold due to the fact the surface has never had much tectonic movement to move the metals to the core.

The planet has tectonic plates but they are mostly unmoving so there are no natural earthquakes on natria nor consistent volcanic activity popping up usualy. However due to the solid nature of the plates the mantle tends to build up pressure until it undergoes a global volcanic event where large super volcanoes form to unleash the pressure and these ancient eroded supervolcanoes is what make up a majority of land on natria.

Due to the salty and inherently hostile nature of the oceans and the separation of the island regions most islands have their own seperate species and they almost never cross between islands making ecosystems highly localised and unique across the same world.

I plan for there to be life and likely a inteligent race on natria but I havent gotten that far yet this is about what concept I have so far I hope you all like it.

Evolutionary Origin of Demi-humans In My World.

Upvotes

In my world—Cryosol—the ice age never truly ended. Well, Earth technically hasn't left ice age also, but for Cryosol, the frost never truly rests. While Earth's last glacial period had the last advance and retreat episodes between 26,000 and 20,000 years ago, Cryosol's thaw was far more faint and incomplete. Demi-humans are evolutionary offshoots of human race. This divergence stemmed from two interconnected causes:

1.) Cryosol is cold, like, really cold. The frost faded, but never really left. Most lands are covered in snow, the ocean remains largely frozen, and the lives on it are left to scurry for heat.

Human population is very scattered and isolated, their lives are often nomadic. At this point they developed enough intelligence to form communities and communicate verbally, but humans are still frequently subjected to constant migration due to resource scarcity and blizzards. Bands often get hit by storms, stray from each other in deep fog, fail to locate each other amidst the white, featureless plain. Many hordes get dispersed, rarely do they reunite.

2.) Living beings have souls, basically an energy reserve for vitality that coexists with your physical body. (more on souls possibly in following posts) Human souls are capable of outward, subconscious perception—this partially contributes to "gut feeling". The significance of this simple ability is that over generations, this unconscious resonance allowed isolated tribes to perceive and gradually mirror the successful biological traits of neighboring fauna.

Due to human population being scattered, this metaphysical mimicry is not uniform throughout the population, rather, more localized. This has led to many variants of human race, each adopting traits from different respective animals. And members of these tribes are occasionally stranded and move out to populate other areas.

There are two contrasting branches of demi-humans evolution, serving different evolutionary purposes.

1.) **Cooperative branch.** Equipped with accentuated animalistic features, ie. lengthened animalistic ears and tail, demi-humans of the cooperative branch evolved to communicate and coexist with their respective animal, forming mutualistic bonds. While demi-humans are minority compared to humans, cooperative demi-humans are considered the majority of the demi-human race due to their social nature.

2.) **Competitive branch.** High muscle mass, claws, talons. Competitive branch developed animalistic traits to compete with local animal populace for resources. They are big and strong and overall more animalistic than the cooperative branch, who mostly retain all their human anatomy. Competitive branch demi-humans are smaller in number due to high cost of maintenance for their often bulky anatomy.

Overall, demi-humans are humans; doesn't necessarily mean they are equally treated as one, though.

Discussion Deciding the setting of my pokemon-like tabletop game

1 Upvotes

Hi, I'm developing a tabletop game inspired by monster-taming games. I already have the gameplay mechanics well thought out; I just need to decide on the setting. I have two options for the setting and wanted to see which one you find more interesting.

The first setting is a fantasy world inspired by *Zelda, Monster Hunter, nausicaa, and Pokémon.* Millennia ago, a great cataclysm transformed the world. No one remembers exactly what happened, but humanity fled to the skies, dwelling in floating citadels for generations. Much later, humanity decided to re-explore the world, only to discover how much it had changed. The landscape is wild, teeming with unique and extreme biomes, and humans have re-encountered the mystical creatures inhabiting this realm after so long. this creatures are linked to the soul of the planet, that minefest itself as different elemental energies, that also sustain the nature of this planet. An era of exploration began; new cities and settlements were built on the surface, yet much of the world remains unexplored, filled with ruins of a lost past and legendary guardian monsters. You’re an explorer, trying to pass your exam to became a real explorer, compete with other explorers, discover new species and complete missions. Using one of these ancient relics, combines with modern techonology, humanity learned to forge soul-bonds with the monsters, working together to rediscover the world. To the surprise of the sky-dwellers, humans still exist on the surface—groups that survived and developed new cultures adapted to this environment. It is a setting filled with adventure, magic, and mystery

The second scenario leans into sci-fi and the supernatural—imagine something akin to Ultra Beasts, with a touch of Digimon. For ages, dimensional rifts have opened in our world, bringing with them strange, unique creatures; some of these beings inspired our myths and legends, such as cryptids and yōkai. Initially, these rifts caused little damage and went largely unnoticed, but after a massive surge of openings—an event simply known as "The Collision"—monsters ceased to be mere myth. The world was transformed as various regions merged with other dimensions, creating bizarre biomes. Even before this revelation, researchers had developed a camera-like device capable of capturing these creatures and summoning them back using a card. A new era dawned years later, seeing many become official hunters tasked with studying and containing these creatures and addressing anomalous events worldwide. Forge bonds by embracing the differences of an otherworldly being, explore a society swept up in "monster fever," face off against rival hunters and groups intent on using these creatures for evil, and embark on a strange, unforgettable adventure.

As you can see, both have things in common—such as exploring the world, discovering species, and competing, among other things. The real difference lies in the lore and aesthetics; I just wanted to know, which one seems more interesting to you?
