If the gargoyle died as flesh and blood, he or she is cremated; if he or she died during stone sleep, his or her remains are pulverized (a disturbing concept, but gargoyles very seldom die in their sleep - except when shattered). The mourners then take the ashes or dust to the highest point in the local area, and hold a memorial service on the departed; by gargoyle custom, everyone is permitted a voice, even the enemies of the deceased. At the end, the gargoyles spread the mortal remains upon the wind, with the words "Ashes to ashes OR dust to dust. All is one with the wind." (This ritual speech was later adapted and used in Western human funerals). The gargoyles then glide out amid the wind-borne ashes or dust, so that part of the deceased will remain with them forever.
Scientific Addendum to Wind Ceremony
Even in peaceful times, Gargoyles, even very old gargoyles, all but never died in their sleep. Sleep for gargoyles is borderline suspended animation. If an old, weary Gargoyle actually made it to daylight and stone hibernation, that bit of sleep would tend to freeze the aging process, the deterioration if you will, and rejuvenate the gargoyle, even just a little bit. They would be much more likely to die after the sun went down, when they transform back into flesh. Even before the iron age, when Gargoyles had little to fear from most any species, when turning to stone was an excellent daytime defense and not a liability, most ancient Gargoyles died just before sunrise, after an exhausting night, rather than after the sun had risen.
So again, the disturbing notion of surviving gargoyle mourners having to pulverize a perfectly preserved stone corpse is a veritable non-issue. The practice of reducing stone remains to dust was a result of gargoyles having to come to terms with stone-sleep having become a vulnerability. If your loved one is already rubble, there isn't much reason to keep the rubble intact. That doesn't mean the process isn't emotionally painful. But not much more painful then cremating a corpse of flesh. Though of course it's more immediate. This is because you are doing the damage, rather than fire. At any rate, that was the custom that evolved.
- After the Sruighlea Cell of Demona's Clan was massacred by Constantine and his men, "True" suggests that the clan perform a Wind Ceremony for the lives lost. Demona suggested instead that they kill those responsible. It is unknown whether any gargoyle returned to the cave to perform a proper Wind Ceremony for the gargoyles killed there. ("Tyrants")
- It has been suggested that part of the reason why Xanatos and Demona were able to revive the Coldtrio through their creation of Coldstone was that the Wind Ceremony was never performed for them after the sack of Castle Wyvern - a concept somewhat reminiscent of how, in Greek mythology, the souls of the dead who were denied funeral rites were unable to gain complete access to the afterlife in the Underworld - cf. Homer's Iliad and Sophocles' Antigone.
- Any gargoyle eggs that do not hatch due to "stillborn" or "bad egg" issues are also given a Wind Ceremony.
