Replicus didn't have access to Skullius' memories, so he couldn't have explained in detail what Skullius had done after this. He only explained the details of his own journey after he took Yuyui and Ferex, met up with Kenno and started on their path to become part of the Severed Union.
He explained the workings of the Severed Union, about the Factions within it and the Immortals, whom he revealed to everyone to be tied to the third Herald on Aigas. He had heard Erlton call this Herald, Aingor. (It went without saying that Replicus explained to Silrat and Theurien what Heralds were.)
Replicus then explained how he got a certain Diviner named Riba from the Severed Union to predict the future for him. He had gotten two revelations from the little man: one related to Skullius being possessed by Fulgardt's WILLS, and another which he didn't tell anyone yet.
At this point, Silrat stopped him.
