The rays of a bright whitish yellow light were radiating out of the dragon's mouth, glowing and pulsing. Their brilliance contrasted with the black sky above the dragon.
Dozens more magical symbols started to arrange into a doubled circle, pulsing in orange light. Vesuvius fed his mana into the circuit just as the previous circle collapsed, and the bright yellow sphere with a white centre and golden edges moved forward, the ray of magma feeding it vanishing.
The magma sphere entered the double circle, and the bright stream of magma once again erupted out of the dragon's throat, passing through the magical square and turning into a concentrated ray.
