Rohan is immensely curious about the functional world. He is constantly absorbing new information and formulating innovative ideas to create new solutions of significance. His lifetime of experience tinkering and enhancing has encouraged him to think beyond the technical manuals and specifications; treating them as safety guidelines. A majority of his personal time is devoted to the abstract and theoretical, delegating mundane maintenance and details to subordinates. Rohan is laid-back, charming, and easy to get along. He is included in many social circles, with a small group of close knit friends which understand and accept his communicative style and personality.

She expects the best both from her self and those she commands.
