Meanwhile, the child within Eva continued to grow, absorbing (in reality, draining) her powers. Since the child was half-mortal it would require power from the non-mortal parent, in order for the child to be born safely and the mother to be safe.
In this case, however, Evalicator, by creating the child in eva magically, had bypassed this requirement. She had also not contacted Stripetail before doing it, which was another strike against her conduct. Without Stripetail's intervention, the child would drain eva of all her powers, leaving her vulnerable to illness, and she would be powerless to prevent the child from releasing its energy. The child would release its energy periodically, and it would serve as a marker on its development. the more it grew and matured, the more power it would require, and the stronger the surges would become.
Since it was half-mortal, a mortal mother, even one as magically gifted as Eva, could not handle its needs on her own. As the child grew in size and power , her powers would diminish. only after giving birth, would her powers return to her; and only if the child survived, if it did not, that power would be forever lost, and eva's life would also be in jeporady.
