Ok, the egg or six times the wise is probably Vivec - 3x6=18 (and 3&6 make 36!)
Vivec then reached out from the egg all his limbs and features, merging with the simulacrum of his mother, gilled and blended in all the arts of the starwounded East, under water and in fire and in metal and in ash, six times the wise, and he became the union of male and female, the magic hermaphrodite, the martial axiom, the six-death of language and unique in all the middle world.
Sword in the center - found in the scripture of love:
The lover is the highest country and a series of beliefs. He is the sacred city bereft of a double. The uncultivated land of monsters is the rule. This is clearly attested by ANU and his double, which love knows never really happened. Similarly, all the other symbols of absolute reality are ancient ideas ready for their graves, or at least the essence of such. This scripture is directly ordered by the codes of Mephala, the origin of six and murder, defeated only by those who take up those ideas without my intervention. The religious elite is not a tendency or a correlation. They are dogma complemented by the influence of the untrustworthy sea and the governance of the stars, dominated at the center by the sword, which is nothing without a victim to cleave unto. This is the love of God and he would show you more: predatory but at the same time instrumental to the will of critical harvest, a scenario by which one becomes as he is, of male and female, the magic hermaphrodite.”
I find that difficult to interpret.
There is a part of the Loveletter that deals with that paragraph:
We begin to see the first inkling of emergence, which by its nature requires the merging of two-fold powers. Inevitably, this leads to another gradient, but this time by forceful process: the Trap of the Lunar God. The Aedra are Named at this time, having lent their hands to what was to be the arena of the eternally impossible: Mundus, or Exactness.
Oblivion to Mundus: debris of all possibility to anchor of all things.
Actually, that possibly refers to the creation of the world and the deaths that were necessary to bring it into being.
Also, perhaps 4.5, halfway between the corners of creation and the troubles, represents the new universe.
