I thought I was a god. No, I thought I was God.
Dr. Slaski

Dr. Oliver Slaski was an Egyptologist who worked for years translating ancient Egyptian texts on mediation. Eventually he came to the conclusion that mediators had the "ability to travel in and out of the realm of the dead without, in fact, dying themselves". He also learnt that mediators are able to travel back in time and transfer a person's soul to another body. He is Paul Slater and Jack Slater's grandfather.
