When entering Flotsam, Vernon Roche gives his name as "Emhyr var Emreis", a spice merchant during the quest "A Rough Landing". Which the guard off-handedly dismisses, rather comically, as a lie; saying: "A spice merchant? Not likely."
Later, the emperor is revealed as the Letho's patron, having supported and funded the regicides as a precursor to his plans to destabilise then invade the Βόρεια Βασίλεια.
