Summary
One day, the barrier to the outside world sealed them in. An entire civilization living beneath a mountain, cut from the outside world. You are born in the Underground, and then you die in the Underground. (Wait, what game was this supposed to be again?)
The Lone Wanderer, eager to find a new purpose after the end of Fallout 3, has inexplicably stumbled into a new adventure.
Now trapped beneath the earth (again), the Lone Wanderer must find her way out of a cavern filled with deadly creatures, mutants, and lovable monsters as she and her trusted canine companion Dogmeat go through a treacherous path that has a much darker secret glitched away just under the surface.
A shared dream has become much more complicated.

Summary
An area where I can put some half-baked ideas I had to put them to rest. Despite the fact that I'm no longer going to use them, I thought that they were pretty interesting, so here we are!

Chapter 2: Two stories from Gaster -

Summary
Waiting for Harry inbetween life and death has consequences for Dumbledore. Death therefore charges him with a test: to redeem someone seen by others as completely unredeemable. That person? Delores Jane Umbridge.
(This is a plot idea that I ultimately don't think I could do justice to, so I'm just putting it out there for someone to use.)

Summary
At the end of first year, Harry pocketed the Philosopher's Stone- in a secret pocket that everyone else missed.
Now, two years later, Harry is in his third year, his friends are having the time of their lives in Hogsmeade, there's an escaped mass murderer running around, and Harry is going stir-crazy. Fortunately, the twins have a solution! Although- they're going to need something in return, and it needs to be good.
Good thing Harry kept that Stone, huh?
And then things go completely bat-shit crazy.
(featuring the Marauders vs 1993, an exhausted Professor Lupin, a bewildered Harry Potter, and an opportunistic Hermione Granger)

Summary
An irritated Pokemon might tell you to stop what you're doing. An irritated animal will probably just attack you. Pokemon, for all their power, would be open books and a breeze to care for to any competent animal handler on Earth. After a fiery death, a professional zookeeper who never outgrew Pokemon games ends up in the world of Pokemon. The entire world is thrown onto its side.

Bookmarker's Notes
I legitimately get excited when this updates. First found on FFN, this is a very detailed fic that is detailed enough to form a wonderful mental image.
Have since gone on to reread from beginning, and again same thing happened!

How Fred and George Accidentally Befriended a Wannabe Dark Lord by map_of_mysteries

Summary
Fred opened the book and began to write. He only got a few words down before the diary absorbed them, the ink vanishing without a trace, prompting George to lean in closer to observe.
“Maybe this is some elaborate joke on Ginny’s part to educate us on proper brotherly behaviour?” George mused, just as new words began to appear on the empty page. Well, that seemed a bit ambitious for a first-year…
‘Hello. May I know who I am conversing with?'
Or: What if the Weasley twins had been the ones who found Tom Riddle’s diary?

Bookmarker's Notes
After accidentally performing human sacrifice with Scabbers, the twins resurrect a baby Dark Lord, who may have absorbed just enough of the twins souls for him to become a redhead. Thankfully, this means he can become a Prewett - but, unfortunately, this means he gets a whole bunch of family. This whole empathy thing is quite the pain.
The author takes great care to give George and Fred their own personalities and interests.

“So, apparently, he did have hair down there,” Fred whispered near hysterically.
Emily wheezed, sounding like a strangled cat. “You waxed the Dark Lord.”
