The Master of Space-Time was a deity, a servant and a disciple of YISUN .
Of immense proportions the Master was a male who stood thirty stories tall with tangled hair, shaggy brows, a skin speckled like the night sky, and with burning stars scattered in his beard.
When the goddess of want, Aesma dared to ask YISUN who YISUN's mightiest servants were - The Master of Space-Time was named as one of those three most mighty.
