You're looking for the Bartimaeus Sequence by Jonathan Stroud, the first book of which is "The Amulet of Samarkand"
A brief summary of the trilogy from the wiki (spoilered for those who haven't read the series yet):
Each of the three books is named for a magical artifact or spell: the Amulet of Samarkand, named after the city of Samarkand in Uzbekistan, ...
tl;dr They kill demons because it's faster, easier, safer long-term, and their experience has shown that they don't really gain much by doing exorcisms (as the demon hosts usually die anyway.)
Killing a demon with the knife is much faster, quiter, and easier than performing a ritual. The ritual requires them to keep the demon in one place long ...
Prince Ombra by Roderick MacLeish. 1982. The boy is Bentley Ellicott; he is a warrior of the borrowed heart. He also has a twisted leg.
...This is why we have a cleft on our upper lips and remember nothing of where we came from. Towards the end of the last century- in 1978, to be precise-a smooth-lipped boy appeared in the world...
...just before we ...
This is "Pact" by Poul Anderson (writing as Winston P. Sanders).
You can read the full story online here
"Ah," said Ashmadai, relaxing. He went behind his desk, sat down, and smiled. "That's quite straightforward, though I admit it will be hard and even painful to do. There's an election coming up-"
"Oh? I understand Satan is the supreme lord of Hell."
The answer for the "why" is found in a scene that was cut from the original edit of the movie, transcribed here:
INT. HALL OUTSIDE REGAN'S BEDROOM
In the dimness, Merrin and Karras lean against a wall, their faces numb with shock as they stare at door to Regan's room. O.S. singing continues.
KARRAS: Father, what's going on in ...
You're looking for the animated films featuring "Unico" :-)
Unico is a baby unicorn with white fur, a pink mane, and little
cinnamon bun-shaped ears, who was born with the very special gift of
making all living creatures lighthearted and happy. His friends
include Beezle, the young Devil of Solitude; Chao ("Katy"), a naive
little kitty who longs ...
You asked for "demon[s] gone good", so I'll pass over the many stories where the Devil never was as bad as he's cracked up to be, such as Keith Laumer's "The Devil You Don't" and Steven Brust's To Reign in Hell. Here are some stories about evil demons gone good:
"The Devil Was Sick" by Bruce Elliott, published in The Magazine of Fantasy and Science Fiction, ...
This is the Winterland trilogy of books by Barbara Hambly.
The blurb for the first one mentions a reluctant ex-dragon-slayer, a black dragon, a goldmine and a request from a King.
When the Black Dragon seized the Deep of Ylferdun, young Gareth braved
the far Winterlands to find John Aversin, Dragonsbane -- the only
living man ever to slay a dragon. ...
There's several types of demons:
White-eyed demons are by far the most powerful. Lilith and Alastair are the only two known ones so far.
Black-eyed demons are in general the weakest in terms of raw power and abilities. They're simply the most common.
Crossroads demons generally have red eyes, and are far more self-serving than other types of demons.
Simply put, we know that demons tend to flash their 'evil eyes' in a few situations:
They are working to terrify a 'normal' person
They are using or preparing to use a significant amount of power
They are confronted by something they fear or respect, but did not anticipate
They are feeling strong emotion
They are trying to remind Sam or Dean that "Hey, I'm ...
This sounds like Clive Barker's "The Yattering and Jack", a short story from his 1984 anthology "Books of Blood". Summary from Wikipedia follows:
Jack's catchphrase (and, if I recall, the last line in the story) is "Que será, será" - or "what happens, happens".
This was also made into an episode of Tales from the Darkside in 1987
This sounds like a segment from the 4th book of James Clemmens' The Banned and The Banished series. The series was published between 1999 and 2003.
The series is a five book epic centred around the journey of the Wit'ch from childhood innocent to fantasy epic hero with her surrounding band of support heroes freeing the land from the Tyranny of the big bad.
As noted by Lorendiac, this does match with "Pact", by Poul Anderson (under the pen name of Winston P. Sanders), available here. This was the answer to Short story fantasy elections in Hell, where they note that Ashmadai is trying to win an election in Hell, and makes a deal with Professor Clipp to have him retrieve the Seal of Solomon in exchange for one ...
You are looking for the Black Jewels Trilogy by Anne Bishop. The first novel, Daughter of the Blood, was published in 1998 and seems to be the one you're thinking of. The eponymous heroine, Jaenelle, is adopted by Saetan, king of hell. He has two sons, Daemon (HB) and Lucivar (UB).
Social constructs in this series are... interesting, focusing on the ...
I believe this is The Shattered World by Michael Reaves. The story takes place 1,000 years after a spell fragmented the world and survivors rely on ships of dragon skin to travel between the remains. A demon is the chief enemy as well.
Centuries after the Necromancer had shattered the world and a group of wizards had bound the fragments together, there ...
The Temptation of Wilfred Malachey by William Buckley (yes, that William Buckley).
From the Publisher's Weekly review:
Buckley has written his first book for young readers, an original and
urbane fantasy listed under Goblin Tales, "stories of the
unexplained." The subdued colors in Gurney's pictures reflect the dark
doings set afoot by Wilfred ...
Crowley is special in several ways.
First and foremost in later seasons:
Additionally, Crowley would have had to have been an accomplished magician even while still human. He did summon a crossroads demon himself, at one point. His time spent in Hell didn't destroy his ambition or cunning either (let's face it, most demons seem downright stupid). His time ...
If I remember the book, I think it has more details than were in the movie. (I don't know if it's appropriate to crossover book-to-movie in an answer like this.)
Simply put, Reagan had started masturbating.
As I recall the whole "possession" thing is a kind of metaphor on the changes of puberty and the church's fear of (especially womens') sexuality.
Sounds like On the Edge - features Alice Little working in law enforcement, and her demon roommate Mr Negative (Negs).
On The Edge is many things; An Alice in Wonderland inspired tale where Alice has grown up in a Wonderland populated by Cats, Demons, and Elves, among other strange creatures. And it is also about our inner Demons, personified through Mr. ...
This is the late Tom Reamy's short story Twilla. The main character is a schoolteacher in a rural area. The little girl's name is Twilla, the teacher is Miss Mahan, and the simple-minded Djinn with the one-track mind is Dazreel.
“Dazreel is back upstairs,” Twilla assured her,
watching her speculatively. “You have nothing to fear.” She ...
I agree with Anthony Grist as you see a distinct decline in the number of individuals that Sam and Dean attempt to save from possession after they retrieve the Colt and the knife. However, as the seasons have progressed, you have also seen the brothers themselves become darker and more blase in terms of killing, and I tend to believe that this is deliberate ...
Technically the main type of "demons" (which are not the same thing as devils) in LOTR are more or less evil individual Ainur, spirits created before the world was made. The Ainur are pure spirits, but they can create physical bodies for themselves as easily as Elves and Men can put on clothing.
Many of those spirits entered the world when it as made. ...
Bit of a longshot, but could it possibly be Constantine? It came out in 2005, stars Keanu Reeves with Shia LaBeouf as his plucky sidekick, and they spend a fair bit of time fighting demons.
The time travel thing doesn't quite happen, but there are a few scenes of "Hell" which looks like a post-apocalyptic LA. Lots of broken buildings and rubble everywhere, ...
You say the animated skeleton is not Marrow from the Piers Anthony Xanth books, but this sounds awfully like Harpy Thyme. The main character is Gloha who is half harpy and half goblin. The demoness is Metria.
The sharing of bone marrow is when Marrow donates some of his bone marrow to Graeboe the giant.
The sharing of souls is when Graboe donates half his ...
You may be thinking of Prince of Wolves by Dave Gross. It is a Pathfinder role-playing tie-in novel.
Summary from publisher:
For elven Pathfinder Varian Jeggare and his devil-blooded assistant Radovan, things are rarely as they seem. Yet not even the notorious crime-solving duo is prepared for what they find when a search for a missing Pathfinder takes ...
Onihime VS (2007), probably. It's 26 chapters long.
Weak, bullied and pessimistic about life, that's Setsuna Kashiwagi. On the verge of jumping off a bridge, a mysterious man appears behind him and offers the contract "10 million yen in exchange for your life in a year." Skeptical at first, he accepts. Waking up the next morning, ...
I think a major factor is just that the show was still in its conceptual stages when Yellow Eyes came into the picture. Heck from season 1 to 2 there is a major jump in the ideas of Demons in the show. I think that "Yellow-Eyes" was a way to highlight the character's significance since he and his actions held central role in the plot from season 1-5.
