Right “ Tarot Redhand “ because even if they still have worshippers on Aber-Toril some Gods could help tip the balance if they were to pick up enough followers from Syithus. There for some Gods would care more (be scheming) if mankind survived on Syithus.
I see what you’r saying “ Werelynx “. If there are some Gods who are fading or have faded away (lack of followers/worshipers) on Aber-Toril that it would really be beneficial for them to have dedicated followers on Syithus. There for in return they help mankind out on Syithus more than the other Gods who don't really need the followers. So I guess in the end only the Gods who would be willing to help mankind on Syithus would be the ones that needed the followers or the ones who are scheming to tip the odds in their favor.
