Corruption:
Yes, the lord has great powers, but anything he does on the planet he has to neotiate with the planetary government.
He can't just build anything he wants down there. The lord does not own the planet (more to this later).
He does not have power over planetary business, except indirectly through interstellar trade or directly through his investment.
This means if he creates a unique monopoly, he and the planet will profit.
He can only have sole monopoly on anything that's not on any planet.
All aside, he and the planet are being watched by imperial troops and intelligence, who regularly report to the Empire the current situation.
If his actions are deemed dishonorable or dangerous to the Empire, he will probably be removed.
Not to mention possible nasty clashes between him and the planetary government.
Virtually buy a planet:
It is possible for a lord to buy and own substantial part of a planet's industry.
But he still has to do this under agreement and laws with the planetary government. If they allow his actions, then he may own the planet's industry.
Another possibility and example is the planet Clasbul in the Sufagnoff system.
This territory was given as a reward for imperial services to the current lord family.
It was a dead rock planet. The lord then invested into terraforming the planet.
If a lord does not have the money he can raise venture money. Venture money is easily to
come by as it's a very profitable and many are willing to lend it for a profit.
So a poor lord doesn't get to own the planet alone at first.
In this case the lord's family had a great fortune due to good investments (probably by same kind of investment).

Terraforming was done, but the lord at the time didn't want it to be inhabitated.
The reason was never revealed. The rumor and the reason for that was given as:
"If an Abh were to want an entire planet for him or herself, it would be something very shameful."
"If that was the case, he should have been ashamed of it as a kin of the stars."
"But there are other points of view. He may have wished for some evolution to occur on the planet before allowing subjects to immigrate to it. Such an idea would be a very Abh like insane idea. But if this were the case, the question remains of why the Sfagnoff family did not brag about it."
In short, Clasbul isn't owned by the lord.
Speakingt of which - It seems like in Abh society there's nothing motivates you to climb social ladder.
You can't become more important person by your achievements as system
govenor and gain more influence within Empire council or something.
Well, there are...
Correct. All the governing powers lies within the Head of State, but the military units are under direct command of the crown prince/princess.
And the candidates are subject to the former Emperor's council.
Yes, lords don't have a say in the Empire, except they hold some government or military position wherein they advise the Head of State. Their advice is their power.
Hence, no corruption possible within the leaders without being ousted.
Corruption still might occure within the ministers.
Being important or having a title is not that important, you get only respect when you deserves it. Title holders get due respect for title but not necessary anything more.
The motivation of the common Abh is any of the following:
-self perfection
-self interest (in something, eg. hobby, harem, Spoor)
-pursuit of something (eg. knowledge, adventure, love, historical note)
-master things (eg. challenges, skills)
-manipulate destinies (eg. as lord, commander, coupid)
-for a higher good (a byproduct)
-pursuit of ideology (not likely)
So anything you want to do by heart, but not for power's sake, but your own sake.
That's why I said they are egoists, and that's why their open tolerance and directness.
