I was perusing The Allspark's mainpage a few days ago, and found a blurb advertising a new fanfic entry by a guy who goes by Dragontail. Instead of beginning with the new entry, I went back to the beginning of his Cybertron fanfic and read it all. It is freaking GREAT. It's the Cybertron story as he interprets it, and he takes a few liberties with canon and continuity, but what results is a spectacular blend of all continuities...something I tried to do myself, but he pulls it off seemingly without effort. Go here and read it. You won't be sorry.
