"It's the same either way, a young or old God of Life, why can't there be two Gods of Life?" Tree Man Gore didn't really mind.
Upon hearing Gore's response, Negris suddenly found out that the followers of the Tree of Life aren't exclusive. Including the elves, they do not reject other religious beliefs, unlike the Church of Light, which sees all non-believers as heretics.
Of course, although the elves don't exclude other religions, they tend to look down on other creatures, which makes them even more exclusive than the Church of Light.
Dealing with such a chatterbox War Giant Tree, Negris easily got all the information she wanted, including the current situation of the elves.
They are still in a state of exile, and the green mist continues to shroud the World Tree, preventing the elves from approaching, in other words, the World Tree has not forgiven them yet.
