Backround story
In the deepest, blackest pits of the ocean a fearsome and terrifying creature lurks. Bending the shadows to his will, few have seen his true form and none have lived to speak of it. For the shadows are his sanctuary, a place of empowerment and revitalisation. Bathed in this inpenetrable darkness he strikes unseen, every attack making him swifter and more powerful whilst weakening his enemy. A unbreakable leash awaits all who try to escape, leaving them at mercy of this horrifying phantom. By sacrificing a fraction of his soul, his pact with darkness allows him break even the most powerful bonds and curses. |n|nWith echoes of the Great War reaching every corner of the earth, this creature, known only as Slark, has emerged from the depths to search for an ancient relic...
