Once Sharnoth broke through and became a Sovereign, Zylarith no longer had to play an active role as her Master.
His aim was to change Sharnoth's Core and help her be reborn as a being of Chaos. With Sharnoth forming the Law of Absolute Chaos, that goal was achieved.
Clearly, Sharnoth now understood Chaos—enough to form an Absolute Law at that. Even in Chaosveil at its prime, her Law would be counted as one of the strongest. But from here on out,
Sharnoth didn't need to understand Chaos—she needed to understand her Law.
And that was the path she had to walk on her own.
The second part of her growth began; it was time for the sheltered bird that Zylarith protected all these years to fly on her own.
Zylarith took away all the Relics he had given to her. The little girl was now alone in the dead world, full of dangerous beasts. The cloak that she had been using all this while to hide from them was no longer with her.
