There once was a sister superior of the Order of Our Martyred Lady holding a village's gate against a seemingly unending tide of chaos cultists. Having fought bravely for an entire day and night, she eventually fell to her knees and died, not without having slain every single foe.
When her sisters finally found her, they buried her in the centre of the village she had saved. When the next spring had arrived, a single purple lily had grown on her grave and was proclaimed a sign of the Emperor and her former squad decided to found the Order of the Virtuous Lily to honour her courage and her sacrifice.
The village later became the capital of the chapter's homeworld. Since then, for nearly six millennia, the flower had appeared every spring.
Hope you like it.
