Vesuvius quietly watched as the image of the dragon before him flared up in the white flames with a blueish tint.
Satisfied, he finally averted his gaze and looked at the medium-sized orbs with a storm trapped inside them. Lightning crackled around them, throwing blue arcs through the empty black space.
'My wings and spikes on my back are already made of similar material to my horns. Their element-controlling abilities would likely be too expensive to implement on all of them, but adding the ability to emit and condense lightning should be relatively cheap, especially with these cores.' Vesuvius quickly analysed possibilities for his following modifications.
With just a single push of the dragon's will, the two orbs of storm melted, turning into glowing liquid looking like liquified lightning.
The liquid floated up and evenly spread into dozens of thin streams, each flowing either towards the crystal wings or the crystal spikes on the dragon's back.
