For the life of me I can not remember the author or any names of the books. Their were multiple books in the series. The story was based on a group of college roleplayers who were transported to the alternate world of their professor (dungeon master). My memory of the stories has faded but I c...

Magnus Bane has a dream about blood streams in a city and darkness on the rise. Chaos with no rules. I think we first hear of it in the second book, where he mentions it. And in Angels of Fire he talks to Simon Lewis after they just send the summoned demon away. Simon says to Magnus he should at...

I remember only one scene, which involved unexpected sudden depressurization (maybe a blown airlock) in a station. The main character rushed to an emergency air chamber and survived, barely. The detail that stuck in my mind is an apparent blood spatter on the wall, which makes the audience think ...

Did naruto retain the sage mode given to him by Hagoromo? Or was it lost after sealing Kaguya? Seeing that Sasuke retained the Rinnegan, I believe it is unfain if Naruto lost some of his extra powers.

I have been recently trying to remember the name of an anime movie that i have hazy memories about. I think i remember it being mecha where humans in what i think is a military unit are fighting these monsters or creatures. I included horror in the title because i can sort of remember parts that ...

We know that Hermione spent most of her time at the library but how about the other three? Didn't at least Bill and Percy get 12 OWL's while being prefects and head boys? How much do you reckon they actually studied and how were they able to do such thing as to get that many OWL's?

While discussing this question, the conclusion was that apart from using parseltongue to open the gate to the Chamber of Secrets, Harry didn't really use any magic and he might as well have been a muggle or a squib during his fight with Tom Riddle. This other question summarizes a JKR interview, ...

Since Dumbledore can understand parseltongue without being a parselmouth, and Ron can mimic enough parseltongue to open the Chamber door without being a parselmouth, it seems logical that someone like Dumbledore who has deliberately studies parseltongue enough to be able to understand conversati...

In Fellowship of the Ring it is shown that Isildur cut the finger which holds the One Ring from Sauron's hand. But at that time, Sauron was very powerful because of his wearing tge Ring. So how could a mere man cut Sauron's finger with a simple blade when Sauron was most powerful?

Ten years ago or more I got a book of short stories out of a library. If I remember correctly is looked old (thick paper, grainy printing) then, so probably an old book. In the book there was a story about a man (scientist?) who has a submersible. As far as I remember it was connected to his shi...

We know that he was very talented but he was also hardworking since even Dumbledore mentioned him being one of the best students in Hogwarts history. This would basically mean that he got the best grades in at least 10 OWL's (if not all of them) while being prefect and head boy. He also explored ...

It is indicated that he already created ring horcrux by the time he approaches Slughorn, it is, presumably, later than he discovers basilisk and kills Myrtle. Though there is no clear indication whether he knew who his mother and her family were by the time he created diary horcrux. On the other...

Who created infinity stones ? Or how they came into existence ? As Dr. Strange has time stone so does he know about it? Also does he know about all of the infinity stones that exists?

So after the snap, we clearly see that the gauntlet is destroyed or at least damaged, but we see Thanos disappearing using the Space Stone to go somewhere else. So my question is, now that the gauntlet is destroyed are any or all of the stones destroyed?

I'm looking for a sci-fi short story that I read a few years ago in a collection, and which I'm pretty sure was pre-2000. The story focused on a main character whose last name (I think) was "Grenfell". He was a scientist who had access to nuclear devices outside of the government, even though the...

We understand from the books that there are multiple parts of the Ministry of Magic and its counterparts devoted to deceiving Muggles, including concocting explanations for Muggle head of states in the event of magical catastrophes. We also know that Obliviators will wipe any Muggle's memory of s...

Hello SFF Are there any Sci. Fi. conventions scheduled in the east coast of USA in the next year?

Around the 70s or 80s, as a kid, I read much of a series about a sort of federation of interstellar-knowledgeable civilizations. They often ran into advanced but pre-interstellar civilizations that they had to contact gingerly. They had a sort of investigator or liaison who worked for them. ...

I have a question in mind about the history of the Choose Your Own Adventure series. Most of the books in the series (including the "young readers" spin-offs) have science fiction and fantasy topics. However, some of the books are in other genres. "Who Killed Harlowe Thrombey" is a mystery; "D...

From the sibling who had the best grades and most OWL's/NEWT's to the sibling who did worst in school? How good did they perform and did any of them even do NEWT's? If two had the same, being a prefect, head boy or playing quidditch would rank them up.

As I was watching Spiderman swing and grab, swing and grab, as he traveled post haste across the big screen, I thought his commute time was quite impressive. How fast does the web fluid exit from his webshooters?
