Samuel is a ranger of the Redcrest Mountains, where the Vermilion Forest branches out to surround Keen Sight. Like some other Keen Sight citizens, he suffers from a medical condition known as “Daymare Syndrome” that causes anxiety disorder, paranoia and hallucinations. Although not proven, there is a possible link between Samuel’s condition and the presence of the government corporation Hexacore Biogenetics in the area.
- According to his early biography, he was originally meant to have a son. His full name was stated to be "Samuel Dyson Walker".
