The Mark of the Outsider
Much more than a mere tattoo, the Mark is an arcane brand, the Outsider's name written in a dead script that no living tongue can pronounce. It is the direct link between the physical world and the eternal cold of the Void.
Only a handful of individuals throughout history, such as Empress Emily or the assassin Daud, have been deemed "interesting" enough to receive it. It grants powers that defy reality: moving through shadows, seeing through walls, or bending time to one's will.
To amplify these gifts, the bearer must carve Runes into whale bones. Bonecharms, on the other hand, offer minor benefits but sometimes whisper to their wearers, a constant reminder that magic always comes with a price.
"I offer you the tools, but it is your hand that carves destiny."
