Did anyone else read the four Elseworlds fanfics? It was about these 
Green, Purple and Yellow robes and changing the Ranmaverse timeline. The 
author said there would be 7 but I could only find 4. If you don't know, 
they are a series of "What if's" Fanfics. Thanks!

The creator, author (Jhon Biles) is on the list.  Last I heard, part 5 
was nearing completion.  Of course, I know of at least two different part 
5's.
