If one listens to the aether, one can hear the vibrations traveling through space. If one listens carefully one can hear what is said. - Lord Caasi on Aetherschreibers
Common for sailors to get lashings for punishment. Sailors would then get tattoos of god symbols on thier back so the thrasher was less likely to whip the symbol of the god.
Others say symbols bring bad luck. They draw the attention of the god and it could be wrathful.
