Umberlee's change was not necessarily a bad thing.
Though the original arrangement had been poor, at least it would not collapse because of her.
Still, many Toril Gods regretted it... Why did Aglaia not want to come to Toril?
At any rate, that kind-hearted girl would not let Umberlee vanish completely, so Toril's Oceanic Law would remain in the hands of their own people.
No one cared about the forest because, in the hearts of many Toril Gods, the Earth Goddess was not even as useful as Umberlee.
Moreover, they knew perfectly well that the Nature Pantheon had originally been invited back by Chauntea so she could preserve herself under Shar's thumb... Look, even someone as stupid as Umberlee knew not to invite wolves into the house!
Umberlee's stupidity lay in the fact that she could not see who the wolves were. She could only see the superficial things before her.
But how could Chauntea fail to understand the consequences of bringing the Forest Pantheon into Toril?
They claimed that the Father of the Forest had appeared because the Elves had arrived... Heh. Amn and the Mulhorandi Pantheon had also appeared in Toril as complete, organized groups!
