So, I guess I need an update on the Shadowrun Ghost situtation. My understanding of shadowrun ghosts comes from Running Wild, page 178:
"For rules purposes, ghosts are considered wild spirits," "that have become imprinted by the dead." They are not lost souls, or spirits of the dead of any sort.
Even
Running Wild doesn't state that they ARE wild spirits, it only says to treat them that way for rules purposes (right before it tells the GM to tweak how much they want ghosts to really act and feel like dead people, or not, to suit their individual game).
It says "most magicians concluded that," and is as vague as the in-character section, never stating with clarity
what they are. There's an awful lot of quotation marks in that section, discussing things like souls, memories, etc, just like back in the IC fluff about ghosts. To me, that implies that the writers intended to leave that decision up to individual GMs, while suggesting they use the core
rules for wild spirits, for simplicity's sake.
