Fearful of what Zara or the elders might do, every child, after leaving the mansion that night, gathered their forces to search for the damn book.
A bounty was placed on the Dynalis underground market and that bounty attracted a lot of interested parties.
So, this search no longer was the Hansley's issue but involved many parties as well.
With the movements the family was making, it shortly became known to several parties that the Hansleys were interested in finding the book.
Their interest in this book made their adversaries and partners curious as to the reason why the whole family was interested in a mere bounty of a few million when they were loaded.
And that reasoning led them to think more than just that. Maybe the book was so meaningful and possessed some secrets and the Hansleys wanted to have a share.
