“ A culture must hide its hands in the arm of their clothing as a sign of respect and peace. When approaching somebody you show them respect by crossing your arms and hiding the hands in the shirt sleeves. Nobody worries about hidden knives and such, it is the threat of magic that this custom was created to prevent.”
“ 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.”
