Rann explains, and its hard to miss cause as more and more media outlets get back up to running,  everyone is tripping over themselves to get an exclusive with this guy, he is that charismatic; that they only wish to help.

  He says that his world,  a small  Earth type world was colonized over a million years ago by astronauts from Atlantis.   For the most part they lived in peace until the world became overpopulated.   They went to war with other Earth colonies and eventually reduced their once paradise to smoldering ruin.   

   They were plunged into a dark age.   While pockets off learning were held on to, most of the survivors were sustenance farmers and raiders.  The learned tried to help them.   Instead of a new golden age, they breed a new world of lazy breeders.    The masses grew dependent on the learned and  refused to work, and demanded more and more from them. 

    New methods of farming, new technologies were developed to easy the demands of the ever growing population.   Each new innovation permitted more and more  people.  Soon the world was covered in riots.    People, scared for their offspring,  raided the public stores and food stolen.    Soon the world was, again, a smoldering ruin. 
   
   Then came Udall.

Udall was not a prophet.  He was a philosopher.  He said 'you do not work, you do not eat.'  Such a simple truth.  After  Udall, charity was a curse.    People walked to their farms over the starving children of their neighbors.  It was a harsh time.    The strong, the smart, the wise, and the capable were all that remained.
  For the next 30, 000 Earth years,   the people of the Udall, as they chose to call themselves, as Kolob, their former name no longer fit,  lived by the simple truth, you don't work, you don't eat.

    They minded their own home.  They raised their own children.   They enforced their own laws on their own lands.    The People of Udall became a race of intellectual giants.   And through years of planned intermarriage and genetic manipulation, each Udall was their own god, king, and scientist.   

    The Udall grew content.   They learn about the universe, but see the wisdom of leaving each to their own.  They will defend their world, if they decide they need to, but for the most part, they like their peace and isolation.

Rann Thanagar, and his consort La Zenn, how ever, are misfits by their people's standards.  They say they are motivated by compassion, an emotion deemed as problematic on their homeworld.     They can not see the world of their ancestor's suffer.     They wish to help.   They wish to give Earth the wisdom of  Udall.

Speaking of the Prince...

Captain Warlock witnessed these two aliens gifting the Prince with meta powers.  And the first order of business, they asked the Prince to prove his worthiness by offing the pesky Moevian Malcontent.
