Bal Sho the Haunted

Drifting through the lonely, remote waterways of the Wreckers' Coast, a lone boat is sometimes seen. In it is a boatman, though none would flag him down even if they had need to travel the seemingly random paths he travels. None welcome his arrival, though when he lingers at the outskirts of civilization some seek him out for strange purposes only they know. He is known to be learned in strange customs and trade in trinkets and talismans to ward off misfortune to any who will risk greater misfortune in bartering with him. One thing is always said of the strange boatman Bal Sho - he is an Ill-Omened man.

Sightings
To most, Bal Sho is merely a bogeyman of sorts, seen in the far distance and avoided as an ill omen. During the construction of the watchtowers of Marrull Vaar one runner was left unnerved after seeing what he thought was Bal Sho watching him from the treeline, though Iron Face dismissed this as him jumping at shadows.

During one of his wanderings into the strange realm he could now access after his experience in the Mirrored Hall, Reeds Whisper heard a flute playing in the far distance, but was snapped out of his reverie before he could explore it. Was that the flute of Bal Sho?

Guimen & Hontari
Several generations ago Bal Sho came to the villagers of Guimen and Hontari, who at the time were still venerating their ancestors in part by sacrificing their unwanted children through exposure to the elements as offerings. Taking the latest child, an infant boy with horns, Bal Sho ministered to the villagers in the "true ways" of Ancestor Worship - though any who could have revealed what this meant are now absorbed into the Song of Flesh and Blood. He returned during the Bronze Tide's advance, buying every head of livestock from the two villages and taking them to the clearing where the children used to be sacrificed. Here the Solar Circle would later find the four wagons of livestock burned in some kind of ritual - not theurgical, not sorcerous - where the Song of Flesh and Blood stopped their advance.

What took place here? Did Bal Sho stop the Fair Folk... or aid them? Did he know the villagers would be ingested into the Fair Folk? And what became of the child?
