And i told u it could had pretty much being because of destructive lvl or because was again a match of God and his shades vs dragons
The War of Vengeance that Nibelung caused literally reminds them of the war in the world's creation which is the war between Phanes + Shades vs Sovereigns.
If u actually read what i wrote
"Well could had been", im just telling a possibility, since we dont know
But you are making them as a legit thing, theres no proof of those Dragons are immortal/cannot die. And not to mention, you basically said something like " Because of they're immortal/cannot die, Phanes had to create his shades and then they manage ti defeat them 40 years later" Which is absolutely wrong. The Four Shades were created were not after 40 years later, literally the same day when Phanes began to fight them.
Same can happend viceversa, some characters have abilities that let them still fight even if their rivals were superior, just as
this dude, even if he fights top tiers in his series he doesnt scale because the only thing keeping him alive is his inmortality
Still, as i explained above, you still have no proof of those dragons having that kind of hax that let them keeping them alive. The Sovereigns fought Phanes and the Four Shades head-on for forty years.
The Main Key of your debunk is;
You assumed that those dragons had immortality hax that keeps them alive. (Which is not true and have not proven)
The literal meaning of the phrase “There was no boundary between Life and Death” that Nicole said in that trailer is:
Life and death were not separated — they blended together or were the same thing.
“There was no boundary” → there was no limit, line, or separation.
“between Life and Death” → referring to the two opposite states of existence — being alive and being dead.
So, word-for-word, it means:
“Nothing divided the state of being alive from the state of being dead.”
In essence, life and death existed as one continuous or indistinguishable state, without a clear point where one ended and the other began.
