Ahsoka Tano was born on Shili, died and reborn on Mortis. To a handful of people that had known her, it was presumed that she had died on Malachor, this time for good.
Ahsoka Tano, sometimes called Fulcrum, once named 'Snips' by a master that had been destined for pain and hatred, lived on.
The Force was not finished with the child it had brought back on Mortis. It might be years, but time was a fleeting concept at best for the mystic energy that touched all living things, binding them together.
When it was best, Ahsoka Tano would rise.
