 Who are the kind of men who are sent to Sararkkad IV?
To have shown himself to one of them would have meant instant loss of prestige. The Occeq of Saarkkad himself was never seen except by a handful of picked nobles, who, themselves, were never seen except by their underlings.

They had no intention of sticking their figurative noses into a battle between the two most powerful races in the galaxy. So Earth had to get a delegation to meet with the Karna representatives within the three-day limit or lose what might be a vital point in the negotiations.
