We learn a great deal more about the giant magician Sinibaldus in the second book of THE CRYSTAL CRUX series, Blue Grotto.
Sinibaldus is a showman. He’s learned that with the power and majesty of the Bellerophon Crystal, theatrics can go a long way. People are generally superstitious anyway. To add a host of gyrations and incantations to the lighting ceremony of the Stone makes it all the more dramatic and mystical. Unnecessary, but dramatic and mystical.
