Drowning Weights
To be married to the Sea is considered unseemly to these coastal people. The sea is like an animal, to be tamed and used, not loved.
Found in hidden, shameful places, these are dinner-plate sized iron disks with square holes in the centre. They are usually an inch thick, with no decorations or designs.
Before adulthood is obtained, one is expected to wear the weights and reject the Sea’s embrace. Those lost, it is hoped, sate the hungry waters. They act as a reminder for those who return.
The genuine, used articles are worth 100gp to collectors, removed enough to not fully grasp what such an item being for sale represents.
Those openly carrying them on the coast are shunned. They might wake up, pinned down and branded.
