I created the setting for the campaign myself, starting from some basic cosmological and cosmic assumptions about things like the nature of gods, and invented a world populated with a number of creatures which had the names of familiar fantasy archetypes -- dragons, dwarves, elves, vampires -- but were actually my own creations, with their own intentionally unique physical and biological natures. I don't know how successful I was in making these creations real to my other players, but they became very real for me, and still fascinate me even though the campaign itself is long over, and I've found that some of the ideas that I made up initially to form the world have turned into things that I believe to be true or relevant to the real world. Some day, I would like to actually write a novel (or novels) set in this world, but I don't have the time to devote to it today. But I've been thinking for some of pulling some pieces of the background out and writing about them here in my journal, since (though incomplete) it's my finest creative achievement to date.
I've been thinking specifically about my dragons, and wanting to try to explain the draconic philosophy of life.
Dragons are highly intelligent beings, more so on average than humans. They are telepathic and highly magical by nature. (Dragons fly not by aerodynamics but by magic.) They are predators by nature, but they are not evil or sadistic. Humans fear them because they are large and powerful, and covet them because of old human legends that drinking a dragon's blood can prolong a human's life to hundreds of years, yet dragons prefer to avoid humans and will only fight them if given no other choice. Those rare humans who have telepathic powers and have the chance to meet dragons often become their friends.
Dragons' unusual outlook on life is a direct result of their biology. They are hermaphroditic by nature, and find the baggage that humans attach to gender perplexing. When dragons mate, anywhere from a dozen to over a hundred offspring may be produced, but the young dragons are extremely frail. Regardless of the size of the clutch, typically only one survives past infancy, and more than two surviving is almost unheard of; yet they do live before they die. An extensive nervous system develops in the dragon embryo before much of anything else does, and the young dragon achieves consciousness and telepathic contact with its mother, siblings, and other nearby dragons many weeks before the embryo forms an egg that will try to live and develop on its own. The young dragons know they are almost all going to die, most without ever seeing the outside world, yet to them this is not a sad thing; it is the way it is. It is part of life and life is good. The adult dragons are in telepathic contact with the young dragons even as they die, which makes them far more intimately familiar with death than we humans ever are. Each dying dragon (and each other creature, the dragons report) experiences, in that last instant as their mind winks out like a soap bubble popping, something so wonderful that their last emotions taste of astonished joy. Thus, every dragon knows (since even the young are in contact with their siblings) that death itself is not something to fear.
The dragon starts out very weak, but as it grows it becomes tougher. The body develops massive redundancy in all its important systems, and what we think of as the brain expands throughout the entire body, so that an adult dragon can even survive decapitation. Their innate healing ability enhanced by conscious use of magic allow them to recover from anything which does not kill them outright, and a mature adult dragon is as close to physically invincible as any mortal creature can be. They never stop growing, though the older they get the slower they grow, and a well established dragon could live essentially forever if he chose; yet it is rare for dragons to live much more than a thousand years. A dragon always reaches a time when he realizes his life should be over, and when that happens, he will die -- usually by inviting some of his close friends to eat him, though sometimes by other means such as power diving into the ground. Their history has taught them that a dragon who does not end his life when the time comes, instead insisting on or being forced to remain alive, will become first listless, then profoundly depressed, and finally utterly insane.
Thus it is that dragons are not prey to mortal failings, not even old age, yet they still cannot live forever without becoming travesties of themselves. Their power is great enough that they could fight nature and see all of their children live, but their wisdom is great enough to realize that if they did, the world would soon be full of dragons with nothing to eat. And their wisdom is further great enough that rather than rail against these realities, they make them the foundation of their philosophy of life.
To a dragon, life is wonderful, but death is also wonderful, a part of life to be anticipated eagerly, not feared. Death is not an evil in the world, it is part of the good of existence. The evil in death is only in a death that comes at the wrong time, and it is equally wrong to live too long or to die too soon. There is no greater crime than to end another's life too soon or force it to go on too long, and there is no greater gift than to help another to die as he wishes at the proper time. When one that we love dies, we can't help but miss them, but we should not be sad for them, and we should only be angry if their death was not timely. And while we live, we should live fully, not afraid to take risks, for it is no better to miss the right time to live than to miss the right time to die.
I think it's a good philosophy of life and death for humans too.
