That was a most informative and interesting post Dostrealt.
We know that in order to exist, deities require folowers/belivers etc. We also know that deities have crossed over from differeing worlds/realities as this is clearly stated in FR Canon lore.
We also can conclude that a deity is nigh on omnipotent and is therefore quite able to be monitoring their faithful on more than one world/dimension/reality.
As Dostrealt has pointed out: [quote:2jko2gou]
If you use Spelljammer in your D&D game, it links Forgotten Realms, Greyhawk and Dragonlance. And part of the rules are that clerics of gods who do not have an active local faith, have diminished power when they visit crystal spheres. So a cleric, druid, paladin, ranger or other divine servant of Eilistraee who travelled to Oerth (or anywhere else in Greyspace) would have a weak bond with their godess.
The weak bond mentioned in Spelljammer means that a divine servant of Eilistraee would be able to gain 1st and 2nd level divine spells, but would not be able to gain the higher spells. (The high-level spell slots, themselves, would not be lost - they could be used for 2nd or 1st level spells.) [/quote:2jko2gou]
I think though, that after time and if there are enough worshippers of a specific deity, then, an avatar of the deity could come through to this new world and grant higher level spells to the clergy of it's religion. I'd envisage up to lv 5 spells being granted. If a greater number of followers are available, then it would be quite possible that the deity would be able to travel to that world etc, and grant the full range of divine spells to its clergy as there is a significant power base of faithful established on the new world.
By using the rules mentioned in 2nd edition AD&D book called "The Complete Spacefarer's Handbook", we now have the ability to have Eilistraeen cults and full blown churches on a myriad of worlds.
The way I see it, it is in a deities own survival interests to establish as many cults as possible, on as many worlds as possible. So, if a deity is ever "killed" on their home plane/world, they still have enough reseve "power" from other planes/worlds in which to sustain themselves until they can be restored on their own home plane/world. This would explain why long dead deities are able to return after being killed off.
In my novel that I'm currently writing, the drow of the world are fairly much the same as on FR's Toril. Lolth [who will be renamed due to copywrite] is the evil goddess who seeks to keep her "children" in servitude and seeks to overthrow and subjugate all races to her will. There will be a full range of gods which will represent all the major races pantheons. Since Eilistraee has suffered a major setback [due to moronism from the part of WoTC

] and that is considered canon lore" I intend that her power has been diminsihed but not destroyed and that instead, she will be restored and ascend to become a greater deity. [ "if you strike me down, I shall become more powerful than you can imagine!

]
Anyway, I'm rambling now but the point is that its entirely possible that Eilistraee has established cults on other realms/worlds and that she is still alive and well on those planes of existence.
