Silas Tagge was a Human male member and chief scientist of the famous and wealthy House of Tagge. He had three brothers, Orman, Cassio and Ulric, and a younger sister, Domina.

Silas Tagge often disparaged the behavior of his more impassioned, nostalgic, and emotional brother Orman. The Baron’s often foul temper no longer came as a surprise to Tagge — rather, he was more shocked when his brother responded to setbacks with placidity and grace. He disliked Orman’s continual pursuit of various vendettas, as he felt that the Baron’s duties were to running the House of Tagge and his own position of power. Tagge placed great stock in the power and value of science, opting to consume food paste rather than the real meat that Orman chose to devour.
