The Obsession: An O.U.R.S. Chronicler Defiant Tale

Isaac is dead, or rather a ghost, and he absolutely despises it. He was a brilliant scientist when he was alive but now he laments and grumbles about his new found cognition, unable to continue his work from beyond his grave. When he is unwillingly pulled into the memories of one of the persons who took him from the realm of the dead, Isaac hopes to learn the reason for his ethereal existence. But there's a strong connection to his captor - how they're victims to their obsession, enemies to their very selves.
