Seeing her baby waiting for her on the other side of the glass and the idea of never touching Jormun again gave Thrud new strength. She remembered everything she had learned about her body and about Awakening during the pregnancy.
How her Awakened baby had made her stronger, to the point of pushing her rainbow core past its limits. She had briefly experienced the power of the white core and remembered its touch well.
'What the heck am I still missing? I have the auxiliary cores, I have a fucking bright violet core, and yet it's not enough to contain the power of my previous rainbow core.' She racked her brain until she noticed that the multi-colored mana wasn't the only thing lingering around her.
Most of the vortex that had previously allowed her to suck in the world energy was still there. Only the parts necessary to form the auxiliary cores had been integrated within her Awakened body while everything else could only try to force its way in.
