On the Illusion of Might
by evevee reviews
We thought ourselves powerful, able to conquer a galaxy with nothing but toys. When we overcame every challenge, breached the space between the galaxies themselves, what use were the words of a race ashamed of their own past? Yet we cannot deny that we were warned, for while a challenge to a human is laughable, a challenge to humanity is a death sentence.

The Havoc side of the Force
by Tsu Doh Nimh reviews
I have a singularly impressive talent for messing up the plans of very powerful people - both good and evil. Somehow, I'm always just in the right place at exactly the wrong time. What can I say? It's a gift.

Call to the Bull Pen
by apAidan reviews
I have a number of stories that are in varying states of completion in addition to the one(s) that are currently works in progress. These aren't ideas that are up for free adoption, and I'm slowly working on these as inspiration strikes. I'll be adding others and moving some of these to active published status as they reach a point where they're completable.

I Still Haven't Found What I'm Looking For
by kathryn518 reviews
Ahsoka Tano left the Jedi Order, walking away after their betrayal. She did not consider the consequences of what her actions might bring, or the danger she might be in. A chance run in with a single irreverent, and possibly crazy, person in a bar changes the course of fate for an entire galaxy.

by Kallanit reviews
Very loosely based on the Reptilia28 Don't Fear the Reaper Death Challenge, whereby Harry gets to relive his life. As do a couple of other people. What effect does this have on Harry's life and the Voldemort Blood wars? Not a Discworld crossover, but some guest appearances by Death's granddaughter. Some character bashing. No Cursed Child or Fantastic Beasts. COMPLETE.

Best Served Cold
by sakurademonalchemist reviews
Unexpected time travel can provide endless hours of entertainment...if you do it right. Under any other circumstances Harry would have done everything in his power to set things right the Gryffindor way. Too bad he's learned a lot since that final battle. Meet the biggest prankster in the Ministry's dreaded Audit department, and with one heck of a grudge to grind!
