Gauntlets, security, accessibility and coordination. Plus falls and loot. Assumptions: A teleport scroll will only take a single adventurer and the items that adventurer is wearing / carrying. If this assumption is incorrect then there are lots of potential problems (how much of the ground they are standing on is teleported with them?) and a very simple ...

In medieval times, this was given quite a lot of thought as castles were designed in most cases to survive a siege. Food is an issue during a siege to be sure, but water more so; this ties into the law of 3s; you can survive 3 minutes without oxygen, 3 days without water and 3 weeks without food. These are of course approximations, but you get the general ...

The Spell Takes a Few Minutes to Work After you rip up the scroll the spell immediately starts working. But teleportation spells are very complicated and the magic takes a few minutes to memorise where all the molecules in your body are located relative to each other. You must stay absolutely still for a few minutes while this happens, and only then are ...

Yes, it's called the Macedonian Phalanx Their main weapon was a giant spear 18ft long, which took them special training to be able to use. The rest of their normal kit was a shortsword and shield, so swap out the shortsword for a short-spear, and you're good. Add in some heavy cavalry on the side in armor and lances. These soldiers were how Alexander the ...

Yes, you have an effective weapon here. Just throw away the useless sword and find a way to get the battery pack to release all its energy at once instead of over three hours. It contains a lot of energy, and will make an excellent explosive device.

Tungsten is very brittle. So brittle that it shatters when hit. Your warrior will be helpless on the battlefield after the first blow. Summary: it will work very poorly.

With the all knowing AI at hand, anything would be possible, so you could handwave this as you see fit, surely? The issues are probably ones of fabrication... people have made piston engines for centuries, because the key elements that need to be made with the highest precision are things that can be handily fabricated on a lathe, and lathes are the ...

It would damage itself more than the opponent. As other answers mentioned, Tungsten would be much too brittle to use, and shatter at the first strike(s). If this can be overcome by changing the metal composition, you would run into different problems like heat dissapation making the handle too hot to hold. Even if a structurally sound and handleable sword ...

Before vulcanized rubber, soccer balls were made with inflated pig's bladder wrapped in leather. Such materials have been available for many centuries. Basketball balls were originally re-purposed soccer balls. But this was after the invention of vulcanized rubber. Basketballs have always been rubber. Needing to bounce efficiently is difficult to achieve ...

3000C is very, very hot. Steel forges and glassblowers operate around 1000C. They wear protective gear just to stand near the stuff. I know volcanologists have issues with their gear spontaneously catching fire due to the heat off of lava flows (again, roughly 1000C). Granted, the flows are a lot bigger than this sword. Still, I think contactless ...

Worked for the Zulu Shaka was credited for the invention of the Iklwa which was a short stabbing spear The Zulu would start combat by throwing a traditional spear before engaging in hand to hand combat with the Iklwa. The Zulu army armed with spears was a credible threat against the English army armed with guns. See Anglo-Zulu War Spears don't need to be ...

My first thought would be the length of the ritual, but this doesn't seem a factor. The next would be if you were forced to return within a certain time, meaning your life would be in just as much peril as before. But since you state they can abandon a quest like this, this doesn't seem an option either. One option could be that you would need to do it ...

If you already know how, and you just need to do fabrication from scratch: jet engines, no question. Yes, building proper turbine blades is a bigger technological problem than building pistons, cylinders, and crankshafts... but jet engines don't need turbine blades. Pulse jets are just about the simplest form of aircraft propulsion you could possibly ...


16

This might be possible, but it will take a large amount of time for this situation to develop. For the sake of this answer I will refer to both the town as well as their inhabitants as Caertydin and Siege. What I think is the most plausible explanation, is that the siege started out as a serious assault, but dragged out too long. Siege didn't cut off ...

As described, your tax system will be difficult to implement The problem with taxing by proportion of income is that it will be very hard to enforce without a ridiculous amount of literate manhours. Every single individual will somehow have to show how much they have earned in the previous tax period, which will be impossible unless they are able to keep ...

As noted in another answer, fabrication is the key. Piston driven steam engines predated working steam turbines by more than two centuries, because any competent blacksmith can make a simple piston and crank (and a rather skilled one might be able to build a multi-cylinder version), and machine tools for this kind of work existed by the late 18th century -- ...

Your blade is about 150 cm^3 of tungsten, roughly 3 kg. That's a lot of mass to heat up and maintain at 3000 K. The surface area of your sword is about 550 cm^2. More surface area will radiate away the energy faster requiring a large battery and also melting the user. All that heat will be right near your face and hands making it possibly impossible to hold ...

A number of options. The castle has a well within its walls so the lord can toss a bucket down and get water for himself. A more modern castle might have hand pumps in appropriate places so maybe no need for a bucket. Assuming the castle isn't in a very dry region, rain could be collected from the roof and fed directly to cisterns, from which the lord can ...

No. From the Macedonian phalanx to the Pikemen these kind of armies have been very effective for almost 2000 years. Provided their flanks were protected by more mobile units. Moving a huge number of soldier with their pikes requires a lot of coordination, every single turn must be done on the order of a commander who might be 100 meters away, otherwise ...

This happened quite frequently in the past, and has indeed quite some advantages. As you state, they are often professional. Their loyalty is with the money, and they will follow whomever pays (the most), or whomever they have a contract with. You need to consider that a hired solder has nothing but their integrity. If a solder is known to back stab and ...

Dirt When all else fails, dirt is reasonably cheap and fire resistant. Build the house out of a frame, and then just slather a thick layer of mud all over the top and sides of the house which should provide a reasonable protection against fire. Also serves as a decent insulator too.

It doesn't work everywhere You need to be in a clearing, or at an intersection of ley lines for it to work. It's easy to reach a suitable spot if you're freely walking around, but if you're being chased by a monster or trapped down a well, you often don't have the time or ability to reach a teleportable spot.

Soccer is not an issue. It has origins dating back to many ancient civilizations including the Greeks, Romans, Chineeze, and various Mesoamerican civilizations which all independently developed similar games that influenced modern soccer which was standardized by the British Empire in 1863. The earliest versions of these balls in Europe were made from ...

The Kingdom that founded Siege has collapsed so it can't officially declare an armistice. Siege don't want to publicly admit this. There is no King to declare an end to hostilities anymore. The people of Siege may think of their kingdom how early medieval Europe thought of the Roman empire: not willing to admit it's gone, occasionally getting behind ...

You show up naked. source The spell takes you, and only you. None of your loot, or supplies, or weapons. Also only live cells; your hair and fingernails stay behind too. If you have time to cache your stuff that is fine but that also means you might have time to figure out some way to escape with your stuff, and hair. These adventurers are pretty ...

There was no refrigeration in the Middle Ages. So ingredients had to either be sourced locally, or preserved in some way. So no fresh oranges in Stockholm, for example. The next problem you have is that some ingredients haven't been invented yet. Just as an example, look at all the different kinds of pepper the hot pepper community has invented in it's ...

It appears that in the Battle of Thymbra, in the Lydia-Persian war (6th century BCE), 100,000 casualties took place in a single day. This was with early Iron Age swords and spears, breasplates and helmets, significantly less advance technology than what you'd see as late as 1000 CE. If the two armies are as large as those at this battle, there's no reason ...

Inflatable game balls go back to at least the mid-19th century, and the ideas behind them could have been implemented as far back as it was possible to make a needle type inflation system. The outer skin of the ball, like very old basketballs (my family had a laced leather basketball that was old in the 1970s) and more recent American footballs, would be ...

Not really, no. Just put steps to the sides of the pole and you'll have a nice quick ladder. You might even design some endcaps for them to be stackable. To expand on this: further advantage of these ladders is that you can more easily carry more and more encumbering equipment needed for this mission: huge hammers for demolishing mechanisms, burning ...
