Bloodline Activation

Draco's body immediately resonated with Eva's transformation. He felt his form shift into that of a Dragonoid. Since the transformation was planned and hadn't been sudden, Draco could distinctly feel the process. and was slowly becoming familiar with it.  

It felt like he had connected every thread of his black mass together, congealing it into a pristine network of power and purity. At that moment, he felt like his power had risen to new heights, a level where even the Gods would have to bow before him.  

However, the stress from doing so was unbelievably immense. In a matter of milliseconds, Draco had to revert back to his normal form lest he rupture his bloodline and… cripple himself!  

That was right, if Draco or Riveting Night dared to overstep their transformation's limits, they would rupture their bloodline source, turning their black/white mass into a waste product.
