Recheck your 'When' section, shadow.
For convenience, these are the ages of the MythWorld, from start to finish.
-AXE AGE: Everything before 570 HC.
-THE AGE OF REASON (Second Era): 570 HC to 430 AE. This was the first of the eon-long ages. This age began when the hero, Tireces, beheaded and burnt the first of the Levellers (this leveller remains nameless). This was a Light Age
-THE WIND AGE (Third Era): 431 AE to 1430 AE. This is the second eon-long age. This age began when Tireces returned as Moagim, who was now the leveller. He killed the new Hero, unleashed the Myrkridia on the world, then died. This was a Dark Age.
-THE WOLF AGE (Fourth Era): 1431 AE to 2430 AE. This is, of course, the third eon-long age. At the end of the Wind Age, Moagim was reborn as, well, Moagim Reborn. Go figure. He was again the leveller, while Connacht rose in the east as the new Hero. Connacht killed the Leveller, and ushered in the Wolf Age. This was a Light Age.
-THE SWORD AGE: 2431 to the present. Connacht returns as Balor and starts on his mission to wipe out most of humanity. Alric is born as the new Hero, and Balor is defeated using the Eblis stone. Balor's head is thrown in the Great Devide. Soulblighter tries to complete the Leveller's mission, but he, too, is defeated.
Also, someone in this thread (I forget who) was talking about Mazzarin talking to Connacht. Connacht wasn't even born when Mazzarin died. Here's the quote that proves it.
"Of all the avatara in the Four Ages there is no doubt that Mazzarin was the most powerful and his death the most salient victory of the Dark during the Wind Age."
-Myth II, Epilogue
Now remember, the Watcher killed Mazzarin (somehow), and the Watcher was busy aiding the bad guys fight Connacht when Connacht was around (he was born at the very end of the Wind Age, after all). So Mazzarin had to be long dead by the time Connacht was fighting the Leveller.
