ver since mankind entered the seas setting sail to lands far away, gifts and sacrifices have been offered to those dwelling in its depths. This could be gods from the deep, or mythic creatures that were said to inhabit the oceans, which would be able to grant a safe passage across the waves.
These days shipping routes depend on sonar and tracking radar for safety,
and solid built cruisers or container ships are able to withstand the harshest waves
and storms, defying the gods and creatures of the deep.
