The characters in my group are currently level 24. My character died and got resurrected as a Revenant. (which was planned). The only one participating in the ritual was Vecna, (he told the other party members to step outside) and he used Raise Dead to perform the resurrection. My character worships Corellon and Sehanine. Vecna is our archenemy-we all have good reasons to kill him, and we will try if given the chance.
However. are there any rules about what happens to the subjects of a god if the god is slain or in other ways defeated? Are there any rules about what would happen to my character and other undead related directly or indirectly to him, if he dies? and what would happen to all the secrets he is hiding?
For the role playing part: Being reborn as a Revenant directly by the wish and might of a god is a pretty huge deal, even if said god is your enemy. What part of a nemesis god would/could you add to your character without ruining the fun? Are there any rules for this?
