a few tidbits i found in Dragon mag (about the only thing there was to find):
Dragon 248, Arcane Lore
Faluzure’s Curse
(Necromancy)
Sphere: Necromantic
Level: 4
Range: 0
Components: V, M
Duration: 1 turn/level
Casting Time: 3
Area of Effect: Special
Saving Throw: None
When this nefarious spell is cast, the dragon is surrounded by a layer of necromantic energy. This aura is completely invisible and cannot be detected by any means save for magic specifically designed to detect necromantic energies; a simple detect magic does not suffice.
While the spell lasts, any creature slain by the dragon via tooth and claw (or other body weapon, such as a tail or wing), rises as a zombie lord 24 hours later. These creatures are under the control of the dragon, and their loyalty cannot be swayed by any means, though they can be turned as usual. However, the number of zombie lords that can be animated via this spell cannot exceed the dragon’s hit dice. Additional undead simply do not rise. This assumes, of course, that the dragon doesn’t eat a slam victim prior to animation; consumed bodies are exempt from the effect.
Obviously, this spell is useless against the undead, but creatures without corporeal bodies, other-planar creatures that can be categorized as “immortal” (e.g., fiends, elementals, etc.), and creatures native (or strongly linked) to the Negative Energy plane are immune to the spell as well. Similarly, any creature with a natural or magically-induced immunity to necromantic magic, or one that simply cannot be raised as an undead creature, is not susceptible to this spell.
The material component for this spell is the dragon’s holy symbol. The symbol is not consumed by the spell.
This spell is granted only to those dragons who worship Faluzure.(5) Spell scrolls are safeguarded so that, if used by any other creature, the undead produced by the magic immediately attack the caster and persist until either they or the caster is slam. Should the caster be slain during such a battle, the necromantic energies that sustain the undead creatures ends, allowing their spirits to depart to the appropriate outer plane.
5. Faluzure, the dragon god of death and decay, is detailed in Council of Wyrms, book two, page 48.
Dragon 205, the Plane Truth Part III
Third day in the Mausoleum: I have lost all track of days and nights. The march sun across the sky, the falling grains of the hourglass — what is the use of these things in Chronepsis’ realm? The span of days is his to rule, within the Mausoleum’s shattered boundaries. Perhaps I have aged here, perhaps I have not. Glin greeted me this morning, his face unlined and horns just budding. By afternoon he was aged again. Could the same be happening to me? Sometimes my handsare hard and worn with care, then fresh with youth. There is no way to tell. Chronepsis banishes all reflections, so that even the smoothest water does not share what it sees.
Glin is impatient to leave. He worries that Chronepsis, sole inhabitant of this realm, will change his humor. I am reluctant to leave. I have never been in the presence of a god before, even a scaled one like Chronepsis. Still I have become used to the presence of petitioners throughout the land, so it is strange to find none here. What becomes of those destined for Chronepsis’ land? Perhaps they are the grains within his hourglasses. Glin is right. It is time (if there is time here) to leave.
First day outside the Mausoleum: Glin’s fears seemed unfounded. Indeed I wonder if Chronepsis truly knew we were there. Perhaps we are still there in the shuffled randomness of the dragon lord's hours, arriving with our heads bowed during its breakfast, leaving quietly again at lunch, only to reappear during dinner counting the hourglasses in their niches.
Outside the limits of the Mausoleum, the land has changed. It is no longer green, but has the sere look of fall. It reminds me of Cormyr. Since the Mausoleum I can no longer count the days from Sigil.
