So according to the letters found around White Orchard, he is died? The soaked letter implied that the convoy Temerians escorted belongs to Velerad's family.

As far as I remember the letter is only addressed to him, so this doesn't have to mean he's dead. I think a lot of the Temerian characters are MIA. For example, John Natalis comes to mind. They are probably in hiding.
