In Norse mythology, the warriors of Valhalla are UNIQUE in their ability to die and rise again.
But they could do so only once, on the day of Ragnarök.
Like the christian armageddon or similar scenarios, I'll make exceptions for when your whole campaign world comes crashing down in big ole apocalypse.
Point is, they come back for battle and not for the unnatural extended long unlife of the undead, and even with that, I would find it tempting to classify ghostly norse ravagers as evil as they go if eyed throught the lense of classical D&D.
Nor is a ghostly parent/lover guardian a "natural state" of a spirit. The natural state of a spirit is repose in its culture's version of the afterlife, not messing around with those still trapped on the mortal coil. Thus, someone who hangs around after death in order to do things on the mortal plane is undead, even in D&D. Read the creature descriptions of revenants, ghosts, haunts, banshees and others- they are undead with unfinished business. Yes, I realize that they are all statted out as evil, but my point (and presumbably the thread's OP) is that does not neccessarily jibe with these creatures' origins. Why is it that a revenant who is trying to kill his killer is neccessarily evil? Why is the ghost of a loving parent who is guarding his children neccessarily evil?
I all Ghost Stories I've read, a parent/lover returning as a ghost tends to mean a bad thing. They refuse to give in the the natural rest of death and sooner or later make life a living hell for their spouse.
People like to go on with their lifes and new lovers, children like to break free of their parents and start their own life. Sooner or later this will bring them fact to face with their ghostly "protector".
As for ghost, banshee's, etc.. they are of course beings with unfinished business.. infact thats exactly what makes them evil. They cling to closely to mortal things, unable to "let go" and turn bitter over all they have lost but fear to pass on to an afterlife without earthly concerns.
As mentioned above, the reasons for being evil are many, but they are still evil.
Infact I very much prefer these kinds of evil as opposed to the "a necromancer who wants to rule the world raised them".
Evil born of pain and tragedy as a much more bitter tang aswell as bringing much more satisfaction to the game when your players put those tortured souls to rest.
Dracula also gained his undeath because of love after all.
On the other hand, I have never found the "necromancer want's to conquer the world" story in fantasy fiction as far as I know, nor have I used it in a campaign of mine so far.
Even if it does exist though.. to conquer the world is not necessarily an evil act. Conan conquered most of his world and he's considered the hero.
The act of raising undead as a means to an end is what would be evil. Doesn't matter if that end is to conquer the world, revenge your own death or protect your favorite toys in your tombs.
Because people in the legends, afraid of their undead countenances, believe they are evil, and that fear and preconception has been injected into the game.
So 3000 years of storytelling are wrong and you are right?
As many people told you here before.. your free to make up your own campaignworld as you choose. Many writers have chosen a different angle when writing about death and undeath as your own examples prove.
But you shouldn't blame D&D and most of it's players for telling fantasy stories the way the've been told since before time, and that simply means undead=evil 99% of the time and for very good reasons.
Was J.O. Barr's The Crow the story of an evil person? No, despite the fact that the Crow meets most of the other requirements to be called a revenant in D&D.
Going on a wild killing spree? I'd argue he's very much evil, thank you. Very cool but also very evil.
Of course the universe of J.O. Barr's Comics doesn't divide the world into good and evil in the first place. Some very, very different assumptions the world is based on compared to D&D.
How about Patrick Swayze in Ghost?
Well here ya go with an interpretation of undead that differs a bit from the more common conception. There are also D&D Campaigns that try this.
Have you tried Ghostwalk or Hollowfaust?
Doesn't change the fact that the classic Ghost Story is about evil undead and that regular D&D tries to capture the classic feeling, not the exception to the rule.
In classic fantasy liturature, Fritz Lieber's Sons of Kyuss from the Fafhrd & Grey Mouser books are also NOT evil- they are the undead defenders of Lankhmar, and among their ranks are past rulers, warriors and wizards who loved the city. They are not immortals- they are clearly described as the walking dead- and yet they are a force- if not for good- then for divine justice and peace in the city of Lankhmar.
Again, noone's stopping you to build your setting on these parameters.
As I have stated numerous times before- the D&D system does not distinguish between involuntary undeath and voluntary undeath. The necromancer who defiles a graveyard to raise an army to take a city is, in game terms, no more or less evil than the priest who asks for volunteers to defend their beloved city as skeletal warriors for eternity.
That is, because by default, the act itself is evil and will turn on the culprit sooner or later. Fantasy fiction is full of people who want to raise dead for love, for revenge, for protection, etc.., etc..
As mentioned above, I have yet to come across a story where a necromancer wants to conquer the world with dead servants.
Similarly, a priest of Osiris (a good greater diety) might find it the greatest honor to be preserved in his god's temple or his Pharoah's pyramid as a (D&D Greater) mummy to keep the temple from being defiled by unbelievers and tomb raiders. Even a valued guard might volunteer for such eternal service. Yet, by definition within D&D, each will be considered evil, despite volunteering for this duty in the service of a good god.
Honor does not equate to being good. Besides, in most pulp fiction and adventure stories, mummies are infact very evil.
There are Games that do cater to a more noble image of old egyptan dead (did you try Mummy: the Resurrection?). But in the "classic" adventure story a mummy is a bandaged monstrosity thats after the life of the protagonists.
This does not make sense!
I hope so.
