Summary
Harry Potter, Auror for the Ministry of Magic, is assigned an international case with MACUSA as an 'expert consultant' - even in 2002 people want Harry Potter to turn up to things based on events in 1981 and 1998 - but whatever these supposed Death Eater sympathisers are doing in Muggle America, doesn't match at all what the Ministry, or MACUSA know about them. These must be something else here...
Cross posted on FFN, will cover multiple years, from 2002 (when Thalia/Luke/Annabeth go to Camp Half Blood) and 2007 onwards (when The Lightning Thief occurs), canon characterisations (no Fem!Harry or demigod!Harry, and Percy is younger than Harry, etc.)

Summary
In one story, Severus Snape killed Albus Dumbledore in Hogwarts, and that was that really, Albus Dumbledore's part in the war with Voldermort was over, Harry Potter would have to take up that burden.
In this story however, after being killed by Severus, Albus finds himself waking up in a cold forest, definately NOT Hogwarts, wandless but not robeless - these were his favourite magenta-saffron patterned robes after all, and gold-blue sunburst waistcoats were so hard to fin-
Righ back with the story.
Albus Dumbledore finds himself wandless, stranded and uncomfortably alone in the North. Well at least he had his watch, and that book on knitting patterns tucked into his inner pocket, so it wasn't a complete loss. Now if he could find out where he was, that would be grandSeries

Summary
What made Elrond Half-elven the person he was in the Lord of the Rings, surely he faced his own challenges and obstacles along the way to being the Lord of Imladris? How did Elvish society actually work, given that by the Second Age most of their grandest buildings were rubble, thousands were dead, their lands were destroyed and those left in Middle-Earth explicitly refused the call of the Valar?
Well here is my take on this relatively unexplored peroid of history prior to the Lord of the Rings

Summary
Roland Durwell's greatest desire is to become a knight. Skilled at arms but disillusioned with tourneys and games, he seeks to win his spurs through glory on a real battlefield. Westeros, however, is at peace following the defeat of the Greyjoys a year prior. With no other options, Roland joins a free company destined for Essos where he will serve as a sellsword, fighting for coin in foreign wars.
But are knightly ideals compatible with the life of a sellsword? What place does chivalry have in a land where people are mere commodities to be bought and sold?
In the fires of war, Roland will forge his destiny through honor and bravery.
