The Astrologer's Vow

There will be a new soul created in the form of a boy.
Created by a descendant of a witch and the descendant of an alchemist.
When all the streams of Time merge into one for the forty-ninth time,
The time will come for the boy to face himself.
The time will come for the boy to decide if he shall bring grave peril or peace to the world.
But to achieve the true knowledge for this decision,
The Astrologer must guide him and teach him the Music of the Ancient,
And he must do no more for it is the boy's choice in the end.
At the moment all streams merge into two rivers: two possibilities.
When the time comes,
They shall merge into one: Amaiti or Alivu.
