Emilio Baza is a Middle-Eastern gentleman claiming to be a Muslim. Emilio is initially one of Gabe's suspects for the kidnapping, but later his attention is drawn to other more likely suspects. He is a vegetarian.
Emilio is in fact the Wandering Jew or more appropriately, Ali, the son of a Grand Master of the Secret Brotherhood who drank Jesus's blood and was given his power. Ashamed by what he had done Ali swore never to use his power for anything. He does seem to possess an acute knowledge of events around him though and helps Grace by leaving a poem, a book on the Grail theory as well as notes in various locations around Rennes-le-Château before revealing his identity to her.
Emilio's bizarre condition has left his finger-tips smooth which is why neither Gabriel nor Grace is able to extract fingerprints from his belongings. At the end of the game he takes Jesus's body through a shining portal.
Quotes:
EMILIO: Please!
MESMI: The reverence is not for you.
EMILIO: I know that.
MESMI: *You* should not be here. You should not be anywhere near this place!
EMILIO: They do not know I'm here.
MESMI: You had better hope not! We have enough to worry about with the baby!
EMILIO: Has there been any confirmation that he's the Kenosh Kania?
MESMI: No. The signs are ambiguous. We won't know for certain until he's old enough to show his will.
EMILIO: But if *you* do not know, *they* cannot know either.
MESMI: I'm certain they do not. But they will take his blood anyway. And it may be enough.
EMILIO: Of course. We must stop them.
MESMI: How? You have been watching Mr. Knight?
EMILIO: Yes. You were right about his family. He has his own destiny to fulfill in all of this. And the girl has found the entrance to the temple.
MESMI: It may be too late. We're almost out of time.
EMILIO: Not until midnight. I have tried to prepare them as best I could, but it is almost . . . cruel to send him in.
MESMI: Do you foresee something?
EMILIO: I have told you, I will not foretell the outcome. But the forces arrayed below will be terrible.
MESMI: He will not be sent alone. When can we start?
EMILIO: Give me time to speak with him. I will call you at the Villa.
MESMI: Very well. Til then.
GRACE: I think it's time we had a talk, Mr. Baza. You left that copy of 'Le Serpent Rouge' at the museum for me, didn't you?
EMILIO: Yes.
GRACE: And the little notes at the center of the circle and the arms of the hexagram . . .
EMILIO: Guilty as charged.
GRACE: I don't get it. If you wanted to help Gabriel and I, why didn't you just be open about it?
EMILIO: I must be very careful that . . . that certain people do not know I am here.
GRACE,You're part of the Secret Brotherhood, aren't you? You and Mesmi?
EMILIO: You are correct about Mesmi. He is with the Brotherhood. But I am not. I haven't been for some time.
GRACE: And Montreaux . . . he's one of the others -- the ones who steal the blood?
EMILIO: Yes. They call themselves 'Adepts of the Holy Blood', but they are vampires, pure and simple.
GRACE: I don't understand. Why doesn't the Brotherhood just stop the vampires?
EMILIO: If you are to understand what we're up against, you must know the whole story. Listen . . .
EMILIO
The Secret Brotherhood are the weavers of the bloodline.
It is a process intricately linked to the stars.
The birth of the Divine One,
the one the Brotherhood calls the 'Kenosh Kania',
can only happen during certain planetary alignments with the constellation Osiris.
Just over two thousand years ago was the last such configuration.
The Brotherhood was expecting something profound.
They tried frantically to read the signs and omens.
There were many branches of the bloodline even back then.
One was the House of David and it was to this branch that the signs pointed.
So the Brotherhood used their influence -- and a bit of magic --
to convince the current heir, Joseph, to marry his betrothed before the date proscribed by Jewish tradition.
Mary conceived.
The signs for the birth were auspicious.
A conjunction of two planets -- Jupiter and Mercury,
created a star, a certain sign of success.
But the Jewish King, Herod, heard of the birth of a Davidic heir and threatened the infant's life.
The Brotherhood took the family to Egypt,
and the young god was reared there;
tutored in the ways of the Infinite.
GRACE: So Jesus was the Kenosh Kania?
EMILIO
Oh, yes.
He was what we had awaited,
the open portal between Man and the Infinite,
the One who could see the fabric of the universe and alter it at will.
But he was also a Jew.
Jesus insisted on studying the Torah, learning his heritage.
And as he read the tales, he became convinced that he was the Jewish messiah.
From the Brotherhood's point of view, it was a limited ambition.
And yet, who were we to tell the Divine One what he was or was not?
GRACE: What happened?
EMILIO
He returned to Jerusalem.
A few of the Brotherhood went with him, to watch over him.
What we didn't realize,
perhaps because we were not Jews,
was that Jesus intended to fulfill the prophecies.
All of them.
GRACE: What about the vampires? Where do they come in?
EMILIO
I will try to explain.
You see, the Brotherhood collected blood samples for study and testing before they selected brides.
There were certain . . . magical rites performed.
There had always been rumors that some of these priests had dared imbibe the blood
-- to steal power for themselves.
Of course, such things were taboo,
and when these rumors surfaced among the initiates, they were harshly scolded.
But when Jesus was being reared in Egypt,
there was a young initiate who envied his strange abilities.
He began to whisper to his friends that to truly serve the Kenosh Kania,
the priesthood ought *also* to be immortal, just like the Kenosh Kania himself.
GRACE: Jesus was immortal?
EMILIO
In a sense.
He could reweave the fabric of his body at will
-- just as he could those of others.
He could have healed his own wounds,
but he chose to perform the sacrifice the prophecies demanded.
It wouldn't have been much of a sacrifice had he rescinded.
GRACE: So what happened with the young initiate?
EMILIO
His name was Sinay.
And one of the boys he persuaded was Ali,
son of the Brotherhood's Head Master.
Ali wasn't a bad boy, but he loved Jesus and liked the idea of living with Him forever.
Fortunately, he approached his father about it one night.
When the head master heard of the heresy he exploded.
Sinay and his followers were expelled.
Only Ali remained, having repented his ignorance.
But Sinay and his followers didn't give up.
Sinay grew bitter; he decided they would *steal* the blood.
He kept eyes on the conclave but could never get close.
When Jesus left for Jerusalem, they managed to keep it secret from Sinay.
He did not arrive in Israel until . . . Until it was too late.
GRACE: So Sinay's group -- the Adepts -- are still after the blood?
EMILIO
Even worse, they found it.
Jesus had heirs -- two sons.
That was the one thing he did agree to do for the Brotherhood's sake.
His son's were only human -- they'd missed the window of Osiris.
But they survived to have descendants.
GRACE: Now the window is open again.
EMILIO
Yes.
GRACE: Is the baby -- Charlie -- the Kenosh Kania?
EMILIO
We do not know.
It depends on how well the vine has been woven.
It depends on many things.
Sadly, it may not matter.
Where the Brotherhood has woven for 2000 years, the Adepts have tasted.
The bloodline grew too broad for the Brotherhood to protect each descendent every minute.
And as the vampires succeeded in stealing here and there, they grew in power and in corruption.
They will resort to anything for the blood;
blackmail, murder, even black magic.
GRACE: They've been mixing the blood as you have, but in their own bodies.
EMILIO
Exactly.
And they've been doing it for so many generations that they have changed, physically.
It is a result of the blood, but even more,
the result of corruption.
You see, the power they have, is stolen. It is not theirs.
Even so, they are strong.
The Brotherhood does not taste of the forbidden fruit.
They're no match for the Adepts anymore.
And the baby's blood may be enough to tip them over the threshold,
even if he is not all we think he might be.
GRACE: So what will happen if they take his blood?
EMILIO
Montreaux will be King of the World -- Rex Mundi incarnate.
GRACE
There's something I've been wondering.
I read about the vampires looking for the Wandering Jew.
He exists, doesn't he?
And it has something to do with the blood of Jesus?
EMILIO
Yes, Grace.
GRACE
But it's not the way the legends claim, is it?
Jesus cursing someone to 'go on'.
EMILIO
No.
GRACE
The vampires didn't get the blood of Jesus, but someone else did.
EMILIO
Yes.
Ali, the head master's son, was among those who accompanied Jesus back to Jerusalem.
For three years he watched Jesus teach.
It was, well, amazing.
But in the end, neither he nor his father could stop Jesus from his course.
The day of the crucifixion Ali's father was so ill with grief that he had to be carried from Golgotha.
Only Ali was left to keep vigil.
Ali could not believe it was ending.
All the promise of the Kenosh Kania,
all of the centuries of planning were being destroyed
-- Jesus was *allowing* it be destroyed.
Something in him . . . rebelled.
He remembered Sinay's words,
and in his grief and rage he thought he might be able to *save* the blood, in himself.
He did not mean to become the Kenosh Kania!
You must understand that.
He simply could not watch that . . . *hope* spill into the ground.
So he drank it.
GRACE
Your fingertips are worn smooth!
But . . . I don't get it!
If you've got the power of the Kenosh Kania why didn't you stop the vampires a long time ago!
EMILIO
I promised my father I would not use the power.
Never.
Not for anything.
It is not mine to use.
It was the only way I could live with what I had done.
GRACE
Never? Not for anything?
EMILIO
No, Grace. Not for anything.
GRACE
But that must be . . . That must be . . .
EMILIO
It is all right. There is work to be done.
GRACE: God, why doesn't he say something!
EMILIO: It is over. God be praised! Everyone is safe.
GRACE: They are? Are you sure? Where are you going?
EMILIO: To the Master. Good-bye, dear one. You must take VERY GOOD CARE of yourself now!
GRACE: Good-bye.
EMILIO: Remember: "When one path to your destiny is blocked another will appear."
