Oborrowind - here is a quote from the book that suggests the writer (who has now been clearly named and identified to Helseth) was aware that other spies were at that table:
a particular Dunmer counselor of Helseth looked like a fellow I had seen in the company of Tholer Saryoni, the Archcanon of the Tribunal Temple. Another, a young Nord woman, has been verified to visit the Imperial fortress in Balmora. Of course, in their cases, they might well have been on Helseth's own business, but I couldn't be certain. I had begun to think myself paranoid as the Prince himself when I found myself doubting the sincere loyalty of the Prince's chamberlain, Burgess, a Breton who had been in his employ since his days in the court of Wayrest.
"He was in need of friendship when he first arrived in Morrowind and eagerly took to me and a few others" so he wanted friendship and chose a consort of spys? Nice one there.
Keep your friends close and your enemies closer. Better the devil you know.
it would seem to me to be more stuff of propaganda.
Bang on - I had overlooked that part. But ask yourself why that particular spy?
many have whispered that while he lost the throne of Wayrest, he does not intend to lose the throne of Morrowind at Llethan's death
You might note that Helseth lost the throne to his half-sister and that Helseth is likely a bad loser. This was his sister's spy who had been successful. He was being killed as a warning to others that they are welcome to spy, but not to harm Helseth's plans - after all Helseth knows the game, eh? And also it may be that initially Helseth trusted his oldest courtier and was a mite peeved at that particular betrayal ... and note the success of that betrayal cost Helseth a Throne and Moprrowind a popular King?
So Helseth likes the game. He knew his oldest retainer so very well and the others at that dinner. And he let them choose their own fate. Basically they now know the price of being both hostile and overly effective, which may handicap them considerably when push comes to shove. The same for any others who have ambitions towards power or revenge.
Also it was so perfect because only his own man - a retainer - was killed. Thus none of the other powers represented there could suggest that he was hostile to them. He was saying I am very dangerous and soo clever and you will not outplay me without cost so be careful to stay within the bounds I set. Look at this loved retainer who betrayed me - he died by his own hand as a result of his lack of taste and style - you, my friends were smarter than he was and treated my table with respect. And as a consequence were perfectly safe.
Helseth may have looked at all the guests at that table directly, but there is one very special message to the Aundae and us. That Helseth does not share the Dunmer aversion to Vampires ... he has after all an Imperial education among other things ... and therefore that was a message to both the Aundae and separately the Dres that they could do business.
