Konrad nods and listens to a run down of the bread sacrifice and the human rib that was found. then offers his observations.
"You say that the locals speak of a place not too far off shore where sailors throw offerings in the ocean to appease the spirit of the sea. These offerings usually take the form of baked food, often in the shape of a very small loaf of bread. This is said to decrease the hunger of sea monsters, so that they don't attack those sailing these waters. I wonder. Could they, knowingly or unknowingly, be trying to appease the octopus-men, or perhaps Iku-Turso?"
It's sailors who do the sacrificing. You say they throw their offerings into the sea at the based of a rock off some way to the north (beyond the pillars). Mostly in the spring, before the busier sailing season, but some do the same at various times of the year. Could spring be an important aspect of the ritual? Or perhaps there's something else about the timing of the offerings that might be important, random, but more common in the spring? Maybe after a storm or the like."
"The sacrifices are made by a fairly small outcrop of rock, beaten by waves, at the limits between the deep waters of the sea and the shallower area closer to Denmark. The shallow area gets wider as one moves south, but at this point it is probably 10 to 15 miles wide. So to the south and east of the rock the sea is shallow, less then 10 paces deep — with many sand banks, marshes and temporary islands — while to the north and west it is much deeper. The obvious conclusion is that something from the deep sea comes up to this place - the closest it can easily approach."
"Have we checked the area around the rock for a magical aura? If infusion of vis is at all a regular thing there, the place may be a weak aura."
"In any case, you say that while inspecting around the rock, you noticed that it forms an overhang at one spot. Swimming there to get a better view, you saw that there is an entrance below, much like a cave. Further inspection revealed that the small cave is quite shallow as well as unoccupied. There were a few bones lying on the uneven floor of the cave. The bones are on the large side. Small ones probably get carried away by the tides since the shallow cave isn't protected from the movement of the water.
One of the curved bones, stuck in a crack in the rocks, contained one unit of Corpus vis. The bone is a rib from a man and is about seventy years old. Magic revealed that the man was in his forties when he died."
"So, what happened there seventy years ago that might have been important? Have we asked around to see if anyone on the island can remember stories about that time? Or was the coprus infused in the last seventy years since the bone got there? In that case, our options for investigation are much wider."
"The bone has apparently been in the sea since the violent death of the man and was picked clean by fish and other sea creatures. It became wedged into the crevice where it was found and became infused with magic on that spot. The bone doesn't really know how that happened, but things have brushed on it numerous times since it became wedged there. Did one of the things that brushed against it infuse it with vis, or were they just fish nibbling on the rotting flesh around the bone?"
"The spell Image of the Man revealed that the bone belonged to a middle-aged man, with a weathered face and the body of someone who had lead a hard life, though not a warrior, as he didn't bear the type of scars that come with battle injuries. The conclusion would be that the man was a sailor or fisherman of some sort. He apparently had that look about him, even though without clothing it was hard to be certain. I know they lose fisherman from time to time. But have we tried to figure out what fisherman might have been lost out there? Perhaps that investigation can be tied to finding out what happened seventy years ago."
"Additional human bones are buried in the sand around the rocky outcrop. However, none of those investigated contained any vis, and most of them seem relatively old. A few, however, proved to be more recent, less than a year old. Are the fact that they are human bones enough to explain the fact that the rib was infused with Corpus vis, or is there something else humanoid involved? The recent bones may come from a storm or other tragedy a year ago. We should check that out too. Could something that happened then have triggered the bone being infused? Have we swept the area to see if there is any vis remaining in any of the other bones? I know that you cheecked some of the bones. How much remains unexplored?"
"So," Konrad concludes, "Those are my thoughts. I know I simply raises more questions. But hopefully those questions will point us in the right direction."
