Oberith Rosenbach, who would later become known
as the founder of this place, commanded an army of priestesses.
They used their holy singing voices and power of light
to protect their allies and the innocent.

These priestesses were once victims of the Black Order.
At a time before Oberith became the Fourth Priestess,
she singlehandedly took on the leaders of
the Black Order to save them.

The corrupt members of the Black Order watched with
a smile on their faces as the young girls screamed
in fear and pain, covered in the blood of Imposters.
Some of them hung on crosses.
Without hesitation, Oberith charged into the scene
and cut down dozens of heretics, saving the girls.
She even built a new home for them.

Since then, singing voices echoed through Remidia Kathedra sometimes.
Soon people started to come from different cities
to hear these women singing His grace.

Some voiced their concern about the dark blood
that tainted these women's souls. Little did they know,
His light already washed the sinful blood away from their spirits.
One by one, the priestesses started receiving His messages.

Finally they'd been reborn into His true avengers.

Oberith created a new division in the crusader army exclusively for these priestesses. 
The members of this new division use their singing voices, which have made them
who they are now, along with the power of holy light
that they've received from God to help the innocent
and support their allies in the battlefield.

They are no longer mere young girls—they're crusaders.
They've set off on a journey to eradicate the forces of darkness
that still lurk in the dark corners of the world and save those who are in pain.

Everything is as He wishes.
