Apart from the Supervisory Bishop of the Priesthood and his close attendants, there were very few who knew the Pope's true appearance.
After becoming Pope, the rejuvenation changed not just his age, but also some of his physical features; at least in memory, His Holiness didn't use to have white hair.
Nowadays, he radiated an Aura of Light all around him, and even his hair emitted a faint golden glow. Held closely in hand, it appeared bright white, but from a distance, it looked almost pale gold, holy and bright.
And as a Church Acolyte serving the Papal up close, in some ways, they were also Church Slaves.
This world had a slave system.
Even in the City of Light within the Capital of the Holy Court, apart from free citizens, there were also those who were slaves.
The Church Acolytes responsible for serving the Papal were raised within the Holy See of Light by people from the Priesthood, especially trained to ensure their absolute loyalty and faith.
