In their time with the sea peoples, Bjoern and Clark were offered to get tattoos. Bjoern, having a high pain tolerance settled for it, and Clark, having a pain phobia watched in horror.

At some point I will design the tattoo Bjoern got. It will probably cover his back and possibly some of his upper arm.
Sea peoples very rarely have tattoos with fine designs and more often have larger portions of their skin coloured black, the designs consist mostly of thick lines. They have a recurring symbol that is considered holy to the sea peoples.
