I think Im in a better state of mind now to suggest.
Just regain essence and when thats done, and I mean a lot of essence, Create an avatar. This avatar would be our corporal form and it would allow us to walk and live as a mortal would, without the added strain of being drained of essence. It does not necessarily have to look like us. Make it clear to our prophet that the avatar is not a god, not a spirit, not a man, not even a beast; simply our mouthpiece. Use this tool to speak with mortals.
Speak again with the elders of the Dead Sun and Clay tribes. Ask them what their spirits would or would not do. Finally, confront the spirits, call their names, tell them to stand up for their people. If the spirits do not come, then clearly the tribes should look upon Nuul for guidance. If they do however come, we should be able to crush the spirits and gain a few slave entities. We are a god after all.
EDIT:
Forgot about Nadani. Welcome Nadani into sentience. treat her like a first daughter, a power as great as Nuul and yet much lower than. Charge her with the watchings of the forests of the world and tell her to strive for balance and moderation.
And about our abusive aspect, NEVER EVER EVER EVER USE IT AGAIN!!! It is against our persona and against logic. It was enough that the man was forced to leave his home and now he must strive forever around the world as a mark of a vengeful goddess. I have an idea: after some time, locate the hunter again and offer him service as a close servant of Nuul, if he accepts, Take away all his pains, give back his abilities, and make him into a hermit of our faith. This might just reverse the actions of our vengeful aspect
