Isbardia — a series by aubie56

An Isbardia Story
Jack and Sue, a couple of highschool seniors, get flipped by magic to a land plagued by demons, mad wizards, and vile sorceresses. They must learn to be a champion warrior and an exceptional sorceress so that they can become the rulers of the magical land of Isbardia. Join them as they fight for their lives and the lives of the good people around them. This story was inspired by some of the characters in the Diablo series of games, but bears only a vague resemblance to the game.

An Isbardia Story
Sue is busy planning the wedding while Jack is out killing demons and monsters. He does meet some interesting heroes on the way as they fight to free Samsor from Hell-spawned domination. This is another Diablo ripoff, so be warned. There's lots of mayhem and magic, demons and monsters, so keep your head down to avoid the stray fire ball or lightning bolt.
