Does Helseth have good friends?
He became count because he was rich and influential enough to buy the position. Getting that rich and influential requires talent of some kind. Inheriting a throne or title doesn't.
Indarys is in the House Hlaalu and thus is in Helseth's house. So he got set up with the duchess, who had an "accident". He definately had a lot of help. He wasn't even selected for Duke, it was already his job by then.
And Helseth does have friends. He is even happily married to a Dres woman. Now Elysana, she's one I can see not having friends. She's like all the bad traits of Helseth exaggerated, with no good traits. I hope that Helseth takes the Wayrest throne one day.
Off topic. It's a fuedal society. It is very hard to rise from the lower classes. Luckily for Indarys and Martin, they started from the privledged classes, and became more privledged. But Martin was the martyr hero, and thus would not be a good emporer. You know why? He had a tendency to martyr himself. Getting yourself killed, no matter for how good of a purpose, is no way to rule and empire.
