For the entire Collaboration Story between myself and Elise McNish you can find them by chapter in the groups Gallery.
The order for the Gallery is Newest first. The very first chapter was written by me and can be found on page 6. This story is an On-Going project that takes place during Final Fantasy 7 and many of it's sub-games.

Jacques and his sister Netzach are both Children of Sephiroth who are overcoming the many difficulties they have to face. Both have undergone experiments at the hands of Professor Hojo in ShinRa.
You can learn most of the information about both Jacques and his sister by reading the story. There is just far too much to sum up in one little post here.
