A graphic for use on a ZBrush sculpt I did using Illustrator.
The sailors who would wear this particular tattoo worked in a very close crew which were hired by ports or even countries to hunt down marauding monsters of the deep or laviation. These monsters, usually being so big, were more than a match for harpoons and nets so the crew would harvest the poison from one particular species of frog (the one that has a star on it's back; the star on the monsters head is a direct reference to the weapon the crew uses to slay it). They then coat all their weapons and portions of the ship itself with the stuff. It was poisonous to other amphibians and fish but not to people and it was an intense purple colour. After so much exposure to this poison the entire crew would start to stain purple/blue, and it wouldn't scrub off.
When on shore they would be allocated their own area of a wharf where the local taverns would deliver drink and food as no land lover would want to go near them or talk to them as their profession was considered suicide. They would all carry this tattoo somewhere on them. As the majority of the sailors would see fighting these creatures as an almost holy battle the motto along the bottom, 'Divinus Mortis', means 'Divine Death'. My Latin is non-existent so fingers crossed the words shouldn't be the other way around.
