Death is lighter than a feather by Haindar reviews
Eternal Wanderer, Lonely Traveler, Chained Sage, and Master of Death. He was known by these and many more names in several worlds, though he found no solace in any name or world. Hallowed in blood, forged in war and baptised in loss, Harry Potter has run far away from the world that birthed him. He traces a path through infinity, intent on reclaiming that which was lost.

Whirlwind Romance by crystalpotter-weasley reviews

SG-Harry by feauxen reviews
Harry's been wandering the multiverse for some time, researching the mysteries of magic. When he comes across the SGC, he can't help but wonder why Ancient technology seems to work WITH magic instead of exploding on contact. This inevitably leads to all sorts of trouble, and a wizard in the Pegasus galaxy. Harry's a cheeky genius, but not the MoD or even overpowered. Much.

Under Goblin Town by AndyHood reviews
There is a reason why the hobbits don't leave the Shire. The story of Bullroarer Took had more to it then what Gandalf knew about. The goblins have a long memory and hold a grudge against any and all hobbits especially Tooks. A story of where Bilbo didn't fall down deeper in the goblin caves and finds the Ring but was brought in front of the Goblin Kings wrath. No Slash, AU No Ring

Back to the Beginning by CrystallineX reviews
The Valar chose many companions to help them create Arda… save for Námo. The Judge of the Dead chose only one companion, who eventually pled for eternal rest. Too bad Námo had different plans. Eons later, Harry Potter woke up in a field of grass. "Sodding dreaming potions…"

The Basilisk of Erebor by Jetainia reviews
Bilbo Baggins had expected to see many things when he entered Erebor for the first time. He did not expect to see a giant statue of a dragon and find a giant snake. Who he then made friends with... MoD!Harry (hinted). Oneshot.

Harry Potter and The Chance at a New Life by kossboss reviews
A small change in Harry's battle with the Basilisk had him slowly absorbing Voldemort's memories from the Horcrux in his scar. Follow Harry as he makes preparations to leave the Wizarding world behind for good and embark on a long and exciting journey into the unknown. Little does Harry expect to be launched into a world of false gods and spaceships. Smart/Powerful/Grey Harry.

Of Dwarves and Witches by AgainstTheMotion reviews
She's a long way from home, but trouble always has a way of finding her no matter the situation. Only this time, it comes in the form of a ragged old man in faded grey robes. It only gets more complicated from there. Thorin/Fem!Harry.

Harry Potter - Alteran by Sashian reviews
The rebirth of an entire race and society is a tall order when this and other galaxies are not safe. What is Harry to do? What he does best, jump in feet first. Rating T for some language and mentions of nudity later on. Pairings HP/HG/LL/other

Avalon, Secret of the Stars by donniedarko81 reviews
A hidden history revealed and the dawning of a new era or the end of another. There is some bashing in this story. You don't like it don't bother reading.

My Neighbour by aliengirlguy reviews
Returning from SGC, Daniel meets his new neighbor. DISLAIMER: I own nothing that you recognize HP and SG1 belong to their license holders. No profit being made. Content rating is to protect my hiney. Warning: A few mentions of straight people, but not a big part of the story.

The End of Magic by AdriaTyler reviews
That aliens exist and live on Earth is intolerable to the muggles. Soon, the genocide of magic has occurred. In 2040, the last of a race choose to sacrifice themselves to send one back in time, to save them all from ever dying in the first place. Going back one hundred years, Harry Potter must bring his people to the stars and away from Earth before all life as he knows it dies.

Wind Lord Potter v1 by Swallow-Tailed Kite reviews
[Halted. Rewritten as Wind Lord, notes on first chapter.] Harry couldn't stay dead. That was fine, he'd always been the adaptable sort anyway. He went among the people as an eagle, helping them triumph against Dark Lords and evil. Unfortunately, Sauron didn't stay dead either, so now it's up to these poor sods to journey far and throw his accursed Ring into a volcano. So he helped.

Failsafe by Hannanora-Potter reviews
Tackling the last traces of magic Voldemort left scattered around Britain, a magical disaster causes Harry and Ginny to wake up in the dungeons of a ruined fortress. It doesn't take them long to realise that something is very, very wrong… Post DH

A Life on Hold by AkiAki-Burst reviews
Seven years... Seven years of peace. Till one day he got careless and took a shortcut back home. The blow came out of nowhere, hard enough to knock him to his knees. Emerald eyes looked into blurry faces before he was hit once again and everything faded to black. Even if he was rescued could he ever heal from it all.

Space Wizard by Jrf Steel reviews
Harry was prepared for his next great adventure, that was until he was blessed and cursed by an old friend with immortality. No pairings in mind. Expect slow updates.

The Roots Run Deep (Into The ground They Go) by SOthisIStheHOBBIT reviews
Hobbits have their own language. Of course they do. Thank you very much. But its a secret, but its hard to keep secrets when you're only a one halfling among 13 dwarves and a wizard. It helped even less when you start to have feelings about one of them... (THORIN/BILBO, Culture clash, made up hobbit language, canon divergence) THIS IS THE NEW VERSION, AND WILL BE UPDATED.

Fall of the Green Wizard by OctoberThirtyFirst reviews
The first spell Harry uttered in Middle Earth brought him squarely under the gaze of Sauron. As the Green Wizard rises, so shall he fall. Slow build-up into powerful!Harry, no romance, Harry joins the fellowship.

Frosty and his Beast by tinybee reviews
Harry's secret as Loki's son is discovered by SHIELD. Fortunately he just so happens to be someone who has helped saved the world a couple of times.

Harry Potter and the Elves Most Fabulous by Steelbadger reviews
Elfling!Harry. Except not. Jaded and cynical Master Auror Harry Potter gets sent to Arda to relive his non-existent childhood. Childhood sucks. Rated M for language.
