I see this in bt other way.
"Age of Darkness"
Tireces kill Leveller Sorangath.
"Age of Reason"
Tireces returnes as Leveller Moagim - unknown hero kills him ( it could be Mazzarin or his son if he had 1 or other mage )
"Wind Age"
Watcher slays Mazzarin - minor event in cycle
Moagim returns as Moagim Reborn. We are not sure is he The Leveller or just a renimated body ( by true Leveller - Mjarin ). Anywas our brave barbarian Connacht kills em both so we are sure that spirit of Leveller is banished for 1000 years once again.
"Wolf Age"
Connacht returnes as Balor. Alrics finishes him off.
Who knows what what will happen next...
