wait - aren't YOU Salazar? Or am I confusing things... O_o
anyway, yeah. Jakob is haunted by "The Shadow of Death" - an evil spirit with the powers of Darkness. He possessed Jakob all those years ago, until a mysterious Druid (the one who I'm talking with in my post) locked the Shadow away in the cloak. He also summoned Kramer. A raven that was to be Jakob's familiar...
anyway, so yeah, Kramer died and the Shadow was released from the Cloak, he took over Jakob, but was unlucky enough to be seperated from him.
Now, The Shadow has Replaced Kramer as Jakob's familiar, and is set on corrupting him to a severe depression in which his mind will break and he'll become a willing Servant of the Shadow.
However, Elizabeth, a nurse in the Syndicate that can control water and other liquids, has helped Jakob out of that mess...
