As noted in the comments, the Wikipedia article you cited contains a description of a Mythbusters episode in which Adam Savage allowed himself to be bitten by a daddy-long-legs. He experienced a "mild, short-lived burning sensation." From this we can conclude that pholcidae can bite humans, but their venom is not toxic to us. While the venom of pholcidae ...

As it stands, the U.S. court system is barred from hearing cases that are not based in some factual question and the person petitioning the court can be potentially harmed by the law in question (standing). Thus we cannot say for certain how the real life court would rule as demons have made no such claim. That said, we do have a few laws that could justify ...

Maybe they could have mating rituals like bowerbirds, in which the males, as part of their courtship display, strive to create visually interesting displays outside their bower (the hut-like structure they build for females to come in and mate with them). As the wikipedia article says: In and around the bower, the male places a variety of brightly colored ...

Universe B does not (yet) have magic mirrors. Universe A magic mirrors do not connect with a corresponding Universe B magic mirror. Sort of like In Mary Poppins, Bert's sidewalk chalk painting does not connect with a sidewalk chalk painting at the destination - Bert, Mary and the kids enter the chalk painting and emerge in the countryside of the alternate ...

Atheism takes a big hit. In this world the group which takes the biggest hit to their belief system is atheists since, well, demons are ripping holes in the universe. The churches will certainly be strengthened but it's also important to think about which churches would be strengthened the most. Faiths which hold that they are the one true faith and all ...

Transport networks act as the lifeblood of modern societies, and just like the human circulation system, it's a lot harder to stop and restart these networks than you might think. To explain why, let's start with planes. At any given time around the world, there's around 9,000 or more planes carrying over a million people in the air. Grounding them all was ...

The key to this is that you don't need to tell the difference until later. If you can't identify which condition your patient has from symptoms alone, the easiest way to deal with it is to treat from quickest and most likely to rarest or most complex. Since you're in a highly occult environment, basic precautions should be taken. Build your facility on ...

It doesn't have to. The First Amendment states (and this is my only knowledge of the separation between church and state): Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the ...

They reproduce like cicadas. Some small creatures take their time about reproducing. Some cicadas take 17 years to reach sexual maturity. That's more time than larger creatures such as dogs and cats. Your fairies may reach sexual maturity only after they are 40 or 50 years old. And then, like cicadas and so many other insects, they mate, lay eggs and die, ...

A Victorian wrought iron gate. https://www.lassco.co.uk/a-victorian-wrought-iron-garden-gate-48543 Wrought iron ..is a highly refined iron with a small amount of slag forged out into fibres. The chemical analysis of the metal shows as much as 99 percent of iron. The slag characteristic of wrought iron is useful in black smithing operations and ...

Flying creatures have a much higher metabolism for their size, especially non-gliding kinds like fairies. If you assume they have a metabolism similar to a hummingbird, then a 10 pound fairy will need just as much food as a full grown man; so, scarcity would be just as meaningful if not more so to them because not only do they need just as much food, but ...

They are busy doing research: Becoming a all-powerful mage isn't that easy you know! The magical world is incredibly complex and requires years of research. The normal world is boring: Would you prefer learning magic, or wasting time in the normal,boring world? The normal world cannot provide what they need: They need magical items for their research. Even ...

Most settings with magic involve some kind of restriction or cost for that magic, to prevent mages from simply using magic constantly to do anything. Sometimes it requires sacrifice, or mages have a limited mana pool that must be recharged by ritual or rest, or even just needing to clear one's mind and focus to cast properly, or it might take time for a ...

I have a unique perspective on this - my mother was a reporter for the Houston Chronicle, on the police beat, and as I grew older she shared with me some of the more gruesome details of her work covering Houston crime. First and foremost, a gunshot to the head is not a guaranteed kill. If the majority of the brain case is intact and the brain stem was not ...

The Churches will have a monopoly on consecrated ground. To put it crassly, they will clean up in the holy ground real estate market. Simply because demons cannot enter holy ground. Therefore, performing rituals to consecrate ground and tracts of real estate will be at a premium. This will them an incredible amount of status, in all areas of social, economic ...

Scientists would wipe out all trace of demons so quickly that religions look even more foolish than today. B. The religion or craft that the spell ritual or prayer comes from has demons as part of its Doctrine, and or mythology. Science deals with everything that exists, if demons exists; they are part of science "doctrine". C. they must be performed ...

Because everyone knows they would die In Universe A these mirrors are well known and studied by some very smart people. Even though the average Joe cannot easily obtain a mirror, it is well known to the average UA resident that if you try to bring anything living from Universe B back into UA it will die. Everyone knows this in UA, it's a simple fact that ...

Mechanisms of death The time to lethality (if ever) of a given shot on the target is primarily a function of shot placement. There are two things people die from over the very short term: destruction of the brain, and loss of oxygen to the brain. The typical way the brain goes hypoxic is through loss of blood (and this can happen in less than 3 minutes or ...

Yes they could. It is true that they wouldn't know how cars, traffic lights, etc work. However, it seems likely that they would realize "I probably shouldn't walk out in front of the big things that are moving really fast". Then other people who know how traffic lights work would start walking when the lights change, so they would learn to follow what other ...

demons, angels, and spirits are real... Set a thief to catch a thief. If you are having trouble with the first of these, recruit one of the second or third on the list to help. If demons can possess a person, angels should be able to also. The angels, though, are austere and haughty - sort of the equivalent of calling in the feds. A very anime-like ...

Never under-estimate the entrepreneurial spirit. As soon as each new alternative form option becomes available and while the knowledge of its availability is still saturating into the general population, there will be entrepreneurs working on how to profit from this new trend. And since clothing needs are easier to predict than dietary or person-hygiene ...

Could an entire neighborhood or even an entire city be that crowded? Sure. Hong Kong’s Kowloon Walled City was probably the densest neighbourhood in history, with more than 1,000,000 people per sq km. Photograph: Alamy Kowloon Walled City was 119 times as dense as New York City.Greg Girard While this example was just 33k people in 6.4 acres, it lasted ...

To bring maternity food in close to their nest so that the brooding mother doesn't need to go very far to eat. The gems and gold are best because they attract not only the bigger hard shelled "warriors" but also the smaller, tender morsels called "thieves", which are great for feeding the hatch-lings.

I'm a current prison guard, here's some insight. I would refuse to book in an inmate with super powers. We can do that by the way, if we feel our facility is not equipped to contain or care for an inmate we will refuse them. That being said you are talking about a massive undertaking, possibly running into the billions. Look up the SCP writing project and ...

There was once a court case where a fellow sued Satan. Several things happened: 1) Satan did not appear for the court date, nor did anyone authorized to represent him. 2) Rather than find for the plaintiff due to the defendant not appearing, the judge determined that Satan, as the head of a foreign power, had diplomatic immunity. Based on that precedent, ...

Before the flat earthers rose into the general consciousness, the crackpot theory of the day was the Hollow Earth. This particular theory was suggested by the otherwise laudable Edmund Halley in the 17th Century and lasted around 100 years before being comprehensively disproven in the late 18th Century. It then lasted in pseudoscience well into the 19th ...

Generally speaking I'm not a fan of hybrid weapons like this, since the general result is that you wind up, as @AndreiROM pointed out "Turning two good weapons into one crappy one." There is an exception scenario though, so that's what I'm going to design to. That exception is when you have something big and fast charging you, and you want to be able to ...

I'm only going to be able to speak for the Catholic side of this. Under current Church law, priests cannot officially work with law enforcement in this manner without being defrocked. Contrary to how many Catholics present themselves with regards to politics, the Holy See recognizes complete separation of the Church from any and all states that are not the ...

I've found it's best to have magic do simple things, and have wizards be smart and combine it for complex operations. For example: Pyromancy AKA moving heat around or creating it Light a Campfire light your way in a cave (heat some metal to have it glow and give light that way) Fireballs (Though you mind need a delivery mechanism... heat up a ball of air ...
