If the leveller is allied to the Dark Gods and aims to destroy the children of Wyrd then if he succeeded in that then its presumable that the world would be a dark evil, myrk, ghol, fetch spider and every other creepy thing covered world.
On the other hand if the leveller is just an evil warrior who seeks solely to destroy then he probably wouldn't stop until he's the last thing left standing.
Of course many do belive in the whole alternating Hero Leveller spirits, but while the evidence is there for the Leveller being one entity the Myth II epilouge clearly states that
"Although the hero of every age of light is different, every dark age is ushered in by the same beast - a transient divinity that seeks only conflict - The Leveler."
Key phrase there, "every hero is different" showing that they don't go Leveller, hero, Leveller and hero again. They just go hero, Leveller, dead.
While the Leveller is a spirit that posses the body of a powerful hero, thus inheriting his memories and part of his personality, the hero "spirit" seems to do no more than give the one blessed with it amazing power, though not remembering any of his former incarnations, suggesting that the Hero isn't in fact an intelligent spirit mearly a messiah like blessing that gives them greater strength, and intellect.
So the cycle goes Hero to Leveller, new hero to Leveller.
The reason that Moagim is the Leveller in the Wolf Age instead of Mjarin is stated in a theory that should be in the Delusions, (ahem GB.)
Mjarin, former hero of the wind age, becomes corrupted by the leveller, because the Leveller can't poses him because he's still alive, he the joins Warlocks, becomes leader.
When the Levellers power reaches its peak, he was supposed to posses Mjarin, but Mjarin isn;t so hot on being killed and possesed, so he makes a deal, I give you Moagim, you teach me Magic. so he ressurects Moagim, maybe he found the body and head and attachted someone elses arms or something.Moagim teaches him the magics, however Mjarin plots against Moagim, because he is not the Leveller he seeks conquest not death. This explains his un-Levellerish actions and makes Myth III make allot more sense really.
So Basically, Moagim WAS the Leveller, Mjarin pretended to be on the Levellers side, pretended to be on the Cath Bruigs side, but as usual was only on his own side.
