In a crossover of vast proportions, the year 2012 brings many worlds together. It will be the most amazing crossover of all time, taking from many science-fiction and mysterious supernatural shows, books, and other worlds. With other stuff thrown in just for fun. 2012 will change the two main crossovers every few days, so don't expect it to stay in one spot.

A small stretch of the truth by an enemy long thought gone leads to a clash of worlds. With Earth unwilling to let an attempted invasion slide and the Colonials having lost too much blood to back down, it seems worlds burning is inevitable. Just as planned.

Born into Darkness

Something I thought about while writing Chapter 129 of AEM. Faith was looking at a reality where she was beaten by Buffy during their fight before the ascension. Faith saw Buffy feed her alternate self to Angel to save him from a poison before she left. This is the story of the alternate Faith who survived; along with a revelation that one member of SG-1 will have to face.
