Is there Iorveth? (The Witcher 3: Wild Hunt)

Rombadenko xs
so far I have only found Roshe, can you tell me how to disenchant the Werewolf in the unnamed task (you need to feed him)?

Such characters from previous parts and the book Saga as Vesemir, Lambert, Eskel, Buttercup, Zoltan Chivay, Triss Merigold, Jorveth, Sigismund Dijkstra, Vernon Roche, Sheala de Tanserville, Summer from Guleta, Cirilla, Yennefer from Vengerberg, Emhyr var will return to the game Emreis, and others.

If only the dwarf Yarpen would be in this mixture of Persians)
I just flattened and goggled from him)))

And nothing is heard about Saskia,

The person who completed the game told me that he had not met Iorvet. Just like Saskia.
