It seems the spirits from our worlds aren't so different. Many back home stay because of unfinished business. But the longer they stay the more likely to become vengeful they are - even those with the best intentions.

Mostly things are pretty simple - the good go to Heaven, the bad go to Hell. Not really sure who makes the judgement on which is which. Course there are those who sell their souls and go to Hell... Actually, maybe it's not so simple.
