More backstory. That reminds me that I wanted to write something about it being partially sunken, but I forgot.
Although it is not widely know to visitors of the village, there are a large number of buildings completely submerged under the ocean. Most of these are either residential or built to store waterproof items. At the time of Abronychus' departure, roughly 1/4 of the town was submerged.
The villagers have frequent contact with merpeople, and usually trade manufactured items for open ocean fish. The sunfish bones that Abronychus' gauntlets are decorated with were acquired this way.
Due to the general lack of outsiders seeing what's going on in those buildings below the ocean, the scales and weird traits that some villagers have, and the fact that merpeople are known to have frequent contact with the village, some rumors have sprung up that the villagers are the result of humans interbreeding with merpeople. In addition to the more obvious reasons that this could be taken as offensive, it is also likely to get the village upset because it is considered blasphemous. It implies that the divine favors of the Really Gigantic Seahorse were not granted by it, but derived from mating with an obviously non-human species.
Bringing up this rumor will usually elicit angry glaring from villagers. Claiming it to be true will probably result in some people dragging the offending party underwater to show them the inside of one of the underwater buildings. Invariably, this results in the outsider almost drowning. It simultaneously gets the points across that the rumor probably isn't true and that saying that it is is going to get people angry. No one has asked the merpeople about this yet.
The town's main exports are fish, bronze objects (there is a small metalworking industry above the ocean), various crafts made from material taken from the sea, and perfect 4x4 inch basalt cubes. It is a guarded secret as to where these cubes actually come from. It is also a guarded secret as to why the origin of the cubes is secret. All the outside world knows is that they make good paperweights, among other things.
