Two years was long enough for him to learn a lot of things. Especially when he was under various trying situations, he would gain even faster. Without those two years of sophisticated experience, he would have freaked out when facing the patriarch. Now, he could calmly tell Vogus about Tannagost, and he had total confidence in controlling the narrative.
He did not reveal everything but only the necessary; those things that Vogus as the descendant of the Tannaean had the right to know. He talked about the ecological disaster and its cause in the Plane of Dreams and projected himself as a professional in handling such events. When talking about the current state of Tannagost, he told the patriarch briefly, "The ecological environment of the planet has been completely rebuilt. Though it was your home ten thousand years ago, you would find it as hard to survive as when your ancestors arrived on Earth for the first time."
