Uriel

Every Angel is a metaphor and a symbol. They all have something they are obsessed with, one part of Gods Creation they are made to cherish and praise. URIEL's favorite thing is Math. He doesn't really need to look at anything or do anything to appreciate Math, so he's a loner and the other Angels try to discipline him for that. They think he is weak and indeed, Uriel isn't any good at sword fighting.

The Angel council welcome back Sataniel, who explored the center of the earth and found a place called Hell, whose ruler taught him about evil and lies. Uriel was investigating how one plays with blocks in 12d. Sataniel uses the power of lying to get a third of the heavenly host to follow him to hell and be reeducated.

The Devil and his third of the host DEMOLISH the heavenly host, because they can use tactics and lies, which angels don't understand and if they learn too much about cheating they become fallen angels.

URIEL however is the Angel of Maths. He might not be good at swordfighting, but he is the most powerful magic user in existence. While the other angels fight a losing war against Sataniel, he builds a machine that makes the Universe run on Math and thus will destroy ALL the angels, intending to sacrifice his own life to keep the world safe from the Devil.

He succeeds.

Human history happens.

Angels are in a sort of coma, but they can still do a few small things. Like how the angel of popularity is trapped in america and is fascinated with democracy, the rule of the popular. So she makes John Hancock sign with a flourish whispers battle hymns into the dreams of Martha Washington and tells Lincoln to grow a beard. Stuff like that.

The Angel of Drugs is doing something just like it to the Aztecs.

Uriel makes the bubonic plague, to find out if it works. (It does.)

Then Apollo 8's crew recites Genesis while outside the world, causing a buffer overflow error.

Uriel tries to keep his machine running for as long as possible, so the Devil is weakened and humans can still use some of their technology to fight back. He is working Celestial Kabballah for that and it's like programming the world using scrabble tiles. Everybody hates him, because systems administrators are always blamed when things go wrong. The work is thankless and he can never stop, but he does it anyways, because he is an Angel.

There is a quarter angel girl named Sohu who can touch and manipulate the tiles too. She is send to him to study under him. She has HEROIC WILLPOWER from her half angel father, who is the greatest Hero of all times and she uses it to understand URIEL through his autism and becomes fond of him. Uriel makes her immortal and unaging... when she's 8. They fall in love and when she has to go take over for her father as greatest hero of the world he edits the highest level of the world, the Bible itself, adding:
Matthew 28:9–20, Mark 16:9–20, Luke 24:1–53, John 20:1 - 21;25, and Acts 1:1–11
And thus creating a new magic spell, that binds their minds and souls together, no matter the distance.

Human scholars dismiss these additions, because as later additions, how can they be part of the secret structure of the Universe? Aaron's friend Ana thinks: What if they were later additions to the secret structure of the universe, analyzes them and finds the Spell.

Thus Aaron and Ana's minds are connected. Also there's a weaker connection between Ana and her cousin Erica, who's going to be important in the Dylan Plot line.
