Employ mermaid escorts. They are smart. They like stuff we have because they accept it in payment from ships crossing their territory. Presumably they can deal with criminals of their own kind. Mermaids associated with the area in question accompany boats. They ward off rouge mermaids whom they identify by their ruddy complexions. The mermaid escorts (...

It could rule. https://en.wikipedia.org/wiki/Ramesses_II Your nation is a shadow of what it was. Foreigners walk your streets and command your kings. The ancient pharaohs conquered many lands and made monuments that have stood 1000 years. Could one of the rulers of old return to restore the glory that once was? Zombies are mindless horrors. Vampires ...

It Knows Too Much Whatever culture created this mummy has a means of making someone literally immortal. Even if the mummy themselves doesn't know the mechanism - though, under the conditions of your question, we can assume they do - they would know where to look to rediscover it. They know the right magic words/the right alchemical processes/the right gods ...

Bomb fishing While your post specifies medieval technology, that does not inherently exclude gunpowder, which was described as early as the 13th century, even in Europe. While sophisticated cannons and firearms are likely unreasonable stretches, simple explosive shells with timed fuses should be entirely doable. While black powder is not a high explosive, ...

Human amusement parks have already different attractions for different sized humans. In many cases a minimum height is required to access an attraction, and in some cases even a maximum height, in order to ensure safety of the visitor. The same concern will apply in your case: a seat designed to hold a human won't work for a rabbit or a cow sized creature. ...

The very first mammals are believed to have been less than a handful of rodent species. Those proto-rats eventually evolved into platypuses, monkeys and even whales. Given enough time and pressure a species can evolve in any direction. For bipedalism, a hooved creature could first evolve to be leaner because it needs agility rather than bulk, and then it ...

I approach this by thinking about contemporary whaling ships, and then thinking about how one could add to that technology. The first thing that comes to my mind is giant crossbow harpoons with drogues attached; the drogues would keep the mermaids from diving and tire them out (as they did for whalers). You could assume that the nations of the time would ...

If the mermaids can survive an extended period out of the water then sling some hammocks across the interior of a wagon. They can ride in what is probably the most comfortable position for a mermaid on dry land.. lying down. The humans could provide buckets of water and rags or sponges so the mermaids can moisten themselves if needed during the day. At night ...

You exposed their attack methods in your previous question: This presents a problem as a group of giant mermaids could capsize a cargo ship and steal its loot. Once the ship is capsized the attack is over. This can indeed be easily achieved by a coordinated attack: some of them holding onto a side of the ship to add an unbalanced load while others push the ...

Mermaid hostages Maybe mermaids don't attack their own kind, or if their own kind are under threat. The ships may keep young or smaller mermaids aboard, under threat of killing them if the ship is attacked. Or perhaps some mermaids serve as members of the crew (or entertainment) beyond just being a hostage/prisoner. Of course it seems like the true answer ...

The Mummy is a regional variation of Vampire An immortal, nigh-unkillable creature with the intelligence of a human and vaguely defined magical powers? Notably, resides in, and rises from, a tomb.. Known to drain victims of their life-force to sustain and repair itself? Yup, sounds like a Vampire to me! The bandages serve the purpose of protecting the Vamp/...

Sedan Chair For most things a sort of Sedan chair or litter would be the preferred mode of overland transport. Swim upriver until you reach your destination city/town, hire a litter from the docks, and get quickly carried to your destination. This would be especially good if your merpeople are comfortable in a "sitting" position and if they don't ...

Are these mermaids susceptible to poison? Toxins? Ships could carry a cargo of substances dangerous to mermaids and dump these into the surrounding water when under attack or even just if being scouted out. Or they might coat darts or other weapons with the poison/toxin and have at it (presumably there would be people especially trained to use these ...

Opposable hands designs have evolved separately in rodents, primates, dinosaurs, and reptiles and in all cases, they seem to have evolved out of a need to climb. While hooves seem like a bad starting place for designing nimble grasping appendages, the mountain goats of today could easily be a transitional species moving in that direction. Mountain goats are ...

That is far to many species without some handwavium you might be able to have 4 or 5 species by separating them onto different continents. Intelligent species can exploit all sorts of environments so they will come into large scale conflict before they have anything beyond stone age technology, Humans wiped out at least two other hominid species with nothing ...

Pterodactly people are called flappers. Because they flap their wings and because the word sounds rude. It can also refer to the female genetalia. Elves (or any small and graceful species) use slurs for effeminate or homosexual men. This also works for any of your species that all look female. Fenireans (miniature people with or without wings) are called ...

Weakspots under the sea A famous Dutch story tells how one sailor heroically jumped over board, swam to the enemy ship and drilled some holes while clinging to it to make it sink. If memory serves correctly, the captain had some beef with the sailor and didn't save the sailir from the water afterwards. The story shows something important. The vulnerability ...

Most Merfolk will Travel Using Crutches There are a lot of answers here based on what merfolk of considerable wealth could choose from, but the idea of persons of normal means owning any sort of vehicles is a pretty new concept. Instead, consider that merfolk are basically no different on land than a 1-legged human. The use of wooden crutches as a means for ...

Let's take a 'Krack' at it: There are a couple of conditions that would need to be met for this to make sense. I'll try to stay away from magic, space travel, panspermia and genetic engineering. This many species will still require some fairly generous assumptions. First, you need to group your species together and decide which bear enough similarity to each ...

Sanctuary planet. It has only been for the past several hundred years that Damarian has existed with its current variety of sentients. The Aeritheans showed up with their own ship but of the rest only the Dragonkin are true natives, the rest having been moved to this planet. This is also true for a number of the nonsentient aquatic and terrestrial species. ...

Just use a wheelchair, it's the best solution for people who cannot use their legs in urban environments. If something more robust is needed then a larger motorised or animal drawn one. Airports and seaports have wheelchairs. No need to reinvent the wheel on this one.

Microbial and fungal spores that can infect animals and plants, ranging from anthrax to plague to wheat rust.

I think in a society where centaurs exist it seems likely that shoes would look different. Probably something akin to ski boots that they could step into and have click into place and then be removed with a bit of cross legged stepping on switches at the back to release the clasps and step out again. More ornate shoes with decorative bits that go up the leg ...

Based on what we know about other marine mammals: Sound travels more efficiently (faster and farther) in water than air, so it seems that medieval tech could produce a loud enough noise to disrupt them, particularly if they have sensitive hearing. https://www.sciencealert.com/this-is-the-horrifying-reason-why-sonar-makes-beaked-whales-beach-themselves ...

Cushions & Boxes: Bypass fixed furniture all together and have a giant pile of cushions, pillows, and bean bags. That way, each species can come into an establishment and grab or request what they need. Helpful wait staff adjust things as needed if they want a good tip (guessing some species don't tip well and will get worse treatment). Make the stuff ...

Now, there are two answers to this question. To which, I will answer with both. Feel free to choose any or all of them. Intelligence Now, while vampires also possess this, a mummy uses it in a bit of a different way. Vampires think small, to put it simply. Mummies raise armies. They used to be a leader, a pharaoh, so why shouldn't they have a kingdom? ...

I think it mostly depends on how fast the mermaids can swim, and for how long. Technically, these mermaids wouldn't be that much more difficult to defend against than normal humans - they might be able to capsize a smaller ship, but they wouldn't necessarily be able to tear through the a wooden hull any easier than a person. Their main advantage is that it's ...

Ram them with a mer-boat. A mer-boat is actually more like a mer-raft or even a mer-submarine. It needs enough floaty stuff to achieve approximately neutral buoyancy. At colder latitudes, ice would be very useful. Otherwise it could be made out of wood (from previously-taken ships) or maybe even something like pumice (we don't need any airspace in the middle,...

As I kid I used to make my own little swimming pool by just filling a wheelbarrow with water. When my cousins wanted to play, we just moved around in a "movable swimming pool". Scale it up to the size of an adult, have some beast of burden or humans moving it, add some more wheels for better holding the load, and you have your transportation for ...
