As Eris forced her purple sun to collapse, she could feel the horrifying stress on her body multiplying by several folds. If not for Sena holding her body together from the inside, she would've already been crushed by her own power. But it didn't end at that; as Sena did more than just hold Eris's body together: She reinforced it.
While the process itself was both painful and complicated, it allowed Eris to exert herself far beyond her own limits. It was as if Sena was performing enchantment surgeries on her in real time to fix weaknesses and repair damage.
If Eris's magic circuits couldn't handle the load, Sena would surgically remove and replace them with stronger ones. If her form didn't fit, she'd modify it, and if her mind failed, she'd flood it with hormones and biological enchantments to make it work better.
