I love that idea. If Gamigo did take it they could just say that the War was lost the Shax won and now we have to reclaim. All the worlds leading up to Sitheran stay the same. Then after they make what they want. Maybe we complete the reclaiming though some big event and everything goes happy again.
Oh no! They didn't win! In my fan fiction...Without over revealing very basic all our characters died, the shax died, the exiles(well they are osirians too) died. Kronos was revived, but his body was once again destroyed, that´s was our characters sacrifice. Oh god! how do i this without revealing everything? oks! Big blast, lot of death, allot of destruction, new curse, osirians lose ability to resonance with any new dragon, and not revealing anything more until i am finish writing that prologue! XD
