Sirene is a striking figure, even among the other formidable denizens of the Train of Lost Souls. Her leathery wings are folded tightly against her back, and her sharp-edged spear rests casually across her lap. Her sullen expression never seems to change, and she seems lost in thought as she methodically sharpens her weapon with a whetstone. Despite her disinterested demeanor, there is an air of danger and power that surrounds Sirene. Her armor is adorned with intricate designs, and her weapons are ornately crafted with an otherworldly elegance. It is clear that she is a being of great skill and experience, honed through countless battles in the service of her infernal masters. While the other denizens of the train might engage in boisterous games and brawls, Sirene remains aloof, perhaps contemplating her fate as she journeys towards the veiled valleys of the vain. Those who catch her eye feel a chill run down their spine, as if they are being judged and found wanting by the fierce erinyes.
