While possible a god puts some of their essence somewhere (i.e. in a mortal FS type person/avatar) hedging their bets about being killed (like a Lich) I think in terms of the class of FS over-all that this is not really the case, otherwise no god could die while enough pieces of its essence was out there in multiple characters, and I would think that the entire pantheon of gods would have dozens and dozens of these kind of followers all over the world and across planes of existence if it were always possible. I think there must be some out with respect to the lore surrounding Bane and Mystra in terms of their ability to cheat being dead. I think that saying all Favored Souls have pieces of their god in them stretches the bounds of credulity - with some exceptions:Storm Munin wrote:To answer your question on details, though the deity is perhaps somewhat irrelevant for the original question, and explaining how the favored soul might be a fatal flaw in the possibility of the death of a god.
A little alternative story then:
The Elflord lounged in his bath savouring the sight of the darkskinned elven maids surrounding him. Eons had passed since he had last enjoyed their grace and beauty.
He sighed and closed his eyes, too long in truth.
Suddenly pain on a cosmic level racked his very being, instantly his eyes opened to bear witness to the lithe creature sitting by his side looking at him over her veil with steely grey eyes. Sparing a brief glance down their bodies his eyes widened as he saw a familiar blade stuck deep into his midriff, shadowflash.. but how..he looked up again.
The maid spoke in her melodous voice "Did you miss me father? at all."
Time stretched as the lord realized he was held in paralyzis.
" I could forgive you for your foregiveness at mother's betrayal, I even forgive how you allowed that pissant elf to sully my name and reputation. But stealing what is mine father? Really? Taking my portfolios.." He voice hardened "..and my people?" that I cannot forgive!
She stood and smoothly glided away to come to a pose a few steps in front of him. He could feel parts of his essence cross the span between them.
In a chilling tone she stated " If you my lord, can take all that is mine. Well, then I will take all that is ours!" With a thought a bow and arrow appeared in her hands. As she trained them on his broken heart she ended the monologue "Aim for the heart isnt that what you taught me when we roamed the planes together? This time I wont miss."
A tear ran down her ebony skin as the arrow pierced her father's heart, ending the life of Corellon, master of the seldarine court. As more of his essence poured into her, the black hair changed into silvery white again and a tall blade appeared at her waist. She was finally complete again... and so much..more.
With the powers taken from Corellon she could smite that inconsequencial ursurper Shevarash with a mere thought and her mother...
Her mother had it coming, Eilistraee grinned, how could the spinner of webs forget what she had let in by stealing from her portfolio? Lolth would soon see how aptly she had named her Lady Penitent.
"No." The voice, it couldnt be! Stunned she looked at the still transfixed corpse in front of her. "I will not allow this daughter and you will release your brother at once!" Another Corellon stood by the corpse now and the flow of essence to her stopped and began anew moving for the breathing Corellon. "As much as I despise what he became, he is my son."
Eilistraee contemplated the demand while Corellon continued "If you had a faithful servant given undeniable access to your spells, how many such servants do you think I have at my call? This was all for naught daughter." A weary sigh left his lips "I die and return again, it never ends does it?".
Bane and lately Mystra did return by somewhat the same means arguably.
Ie by placing part of their very being elsewhere for a time.
In essence a favored soul is a broken off part from a deity?
Thus the natural spell casting?
Thus it doesnt matter if some other deity picks up the fallens portfolio?
"Though Ao had decreed that none of the gods fallen during the Time of Troubles should be reinstated, a complex convergence of factors regarding Torm's death led the overgod to make a single exception in his case, resurrecting him and elevating him to the status of lesser god" I believe that AO grants portfolio's and abhors a vacuum in terms of maintaining balance between Law/Chaos/Good/Evil and... (Waterdeep, Richard Awlinson, TSR, 1989) "after Bane's death, his portfolio was divided among the newly anointed god Cyric and Bane's own half-demonic son Iyachtu Xvim. Upon the death of one of the greatest forces of evil in existence (Bane), all of Faerûn breathed a sigh of relief; however, in 1372 DR, Bane was resurrected, destroying Iyachtu Xvim and reestablishing his church.
