An Investigation into Hero's Herb

Tracing this "ribbon-like" stretch of flora running from south to north, I found myself utterly mesmerized by the enchanting Hero's Herb that blankets the Ancient City of Vill in a vast, sea-blue breath.
The Hero's Herb emits a gentle blue glow, and when my fingertips brushed its blades, I felt a faint vibration-as if the grass was whispering to me. The nearby forest wardens say this is the voice of fallen warriors, communicating their longing through an unspoken tongue.
Though I am a scholar by trade, I am deeply moved by the legend of the Hero's Herb: the souls of warriors who perished in the Asterleeds Independence War return here, and so the Hero's Herb grows tirelessly toward Asterleeds, eternally guarding the land for which they once fought.
