In the end, Torne manages to transform Dax's soul into a ghost after his death. He used an ancient ghost technique to force the creation of new creatures of this type.
That was not the best way to obtain a ghost, as it diminished the power the being had in life. However, Torne did it to please his master and soon gave Vicente another slave.
Vicente didn't want one of his mother's murderers by his side, so before leaving the area, he ordered Dax's ghost to go after any members of the Bone Mountains who appeared there.
Ghosts couldn't go far from where they were created, so Dax's ghost couldn't go to the Bone Mountains headquarters to wreak havoc.
But Vicente had already expected the elders of that sect to go to the place where he had dealt with Dax, so the limited range of this new ghost wouldn't be too bad for his plans.
