SG-Harry by feauxen reviews
Harry has been wandering the multiverse for quite some, researcing the mysteries of magic. When he comes across the SGC, he can't help but wonder whether Ancient technology is working WITH magic instead of exploding on contact, and this inevitably leads to all sorts of trouble, and a wizard in the Pegasus galaxy. Harry's a cheeky genius, but not MOD or even overpowered. Much.
