Pilgrimage of The Saint
On the sun parched front steps of the Abbey of the Immolated Martyr, a young pregnant girl was found on the verge of death. The Abbey was built into the precipitous cliffs of the Lady Mount at the scorchmost tip of the Chalice with only scorched desert for a hundred miles in every direction leaving no indication of how the girl could have reached it.
Dying without a word of explanation giving birth to a girl child, the woman took her mystery with her to the grave and the sisters of the abbey took the baby on to raise her.
The girl was named Argent Rose and entered training to be a member of the Adepta Sororitas, excelling at every required skill. On the morning of her final graduation however she announced that the Emperor had visited her in a dream and told her to walk the land until she came to a full understanding of his mission for her. She left the abbey on foot and set out with no provisions into the burning wastelands of the Hellgrove. Over the following years, Argent Rose walked the land, administering to the poor and needy, speaking with the people and learning all that she could about the ways of mankind.
She made her way up through the Chalice and into Lapitar, visiting Qualitat by sea before going on into Paelar and finally Kaltirey, making her way through the streets of the capital before heading out across the frozen plains further and further chillward until she reached the Abbey of the Cold Heart of the Emperor at the freeze. Here she paused only long enough to strap on her power armour and take up her holy bolter for leaving once more.
This time though, as she walked south, she no longer helped the meek, she hunted the wrongdoer, the mutant, the heretic... and she exterminated them. Years of extermination passed as she made her way back down toward the Lady Mount until when she finally arrived, her fame and notoriety had spread. Thousands of pilgrims and Adepta Sororitas were waiting for her and proclaimed her The Saint.
She spurned this title but proclaimed that the Emperor had chosen her for a new task now that she had proven her worth. Taking hundreds of battle sisters with her to the stars, she began a Crusade of Immolation that continues to this day, taking her holy fury into the night.
The Path of The Saint became a huge lure for pilgrims from across the sector and the already strong Ecclesiarchal presence became even stronger, Sisters of Battle guarding the many shrines erected along the route of the Path.
