"Then this personage shall lay before you the events of the Fourth Darkening, one in which he was yet herald of Greed," said Zagan. "First, there was Ijiras of En Vexelann, or that which you know as the never-ending storm of the Northwastes."
"Demons live even in the Northwastes?" said Li.
"Three centers do we demons inhabit. En Arkennan, the center of chaos – that is where the seven swarms originate. En Vexelann – the center of the eternal storm. And En Okeas – center of the watery depths that has now been warped into the sealed Abyss."
"I see."
Seeing that Li had no further questions, Zagan continued. "Ijiras was mighty indeed, rising to the top of the storm, feasting upon the strongest of demons of frost and wind and lightning until finally, she found herself bored of the challenge of En Vexelann. She left her home and came to En Arkennan, challenging all leaders of the seven swarms and finding herself triumphant.
And so the fourth demon war is finally revealed just a bit! This will give some context to future events and whatnot.
As fun side notes:
-During the fourth darkening, the demons were probably almost at their weakest. Before the third darkening, the demons of En Okeas would have been a formidable seafaring force, but with them being lost to the Abyss, the demons lost all of their maritime capabilities.
-Amon fought with Zagan in his swarm during the fourth darkening, and their failure made Amon realize even more how the principles of the demons were failing them, because if they just became one real army under a real general, then they would have done a lot better. This drove him further into exploring new powers which leads to today.
-As for Pride's power level, he would register as a level 80 demon, but the abilities he has from cultivation and other eastern shenanigans that cannot be registered on Elden World game mechanics would actually have made him on par with a decked out level 100 character, though not on par with Li. Certainly would have given Li a good fight though, easily among the hardest he would have had so far (not that that is saying too much though).
-A very rough numerical estimate of Li's power as a level 100+ character would be something around level 150, though of course this is a very rough classification.
