According to Maziz Kazire, the main divide in the entire known universe was between Magic and Technology.
Entire star systems were formed around each power structure and immeasurably deep wellsprings of power lay hidden behind each faction's fortresses and outposts and core planets.
For many millennia the endless war between the two factions had raged, ebbing and flowing in either direction but never managing to cross the critical line of no return to see either one faction rising to the top.
One reason was because they were quite balanced in terms of power. Even if one faction managed to make a breakthrough and gain an advantage over the other, it was never quite enough for a decisive victory.
They always fell short of overcoming the single biggest barrier to conducting a thorough purge.
Distance.
