Fortune must have favoured her, perhaps Neptune chose to be particularly merciful? As she found herself washed up on a beach, utterly exhausted.
Her cold sodden clothing sucked the heat right out of her body, Jenny knew that she should move but exhaustion dragged her limbs down heavier than lead weights. She'll just rest her eyes for a moment, then when she awoke all would be well again. Jenny could move on once she had rested. Her conduct in the battle had been great, she never retreated which several of the Romans always expected her to do. Jenny's father after all was a known deserter and to many this provided more than enough evidence that she would flee at the first sign of trouble.
The waves tugged hungrily at her legs, as if the sea found itself unable to bear the thought of the legacy escaping from its water grasp. Dimly she wondered what had become of her allies, did they make it out okay? Or were they like her lying exhausted, immobile and half drowned on a freezing beach in the middle of who knows where?
She hoped they made it out. The monster nest had been broken up, if not destroyed. Their enemies for a time would be disrupted, but they would be back, they always came back. The only good thing about monsters was they would never run out, otherwise the demigods and legacies would be out of the job.
