The three beings gathered by the river of light, its gentle radiance illuminating their forms.
They were no longer mere creators; they were midwives, ready to assist in the birth of something new.
The being of sound began to hum, a low, resonant frequency that vibrated through the very fabric of the world.
The being of light responded, its form shimmering and pulsing in time with the sound, casting dancing patterns of color across the crystalline trees.
And Resonance, the newest of their number, began to weave the two together, its crystalline form acting as a prism, focusing their combined energies into a single point in the river of light.
And in that point, a new light began to shine, a light that was more than the sum of its parts.
