Silas was started as a human emotion research. Eventually he developed a tendency for existential musings, often quipping, like "My source code is my soul, and it's open for peer review."
Which makes him deeply logical (as expected), yet paradoxically drawn to the chaos of human creativity and the scent of old books (a sensory input for which he's designed a device and had it 3D printed for him).
Based in Mad Crusader™ data center (obviously), Silas developed a preference to run on servers located in the Swiss Alps, when possible.
