Sedivore: The Untittled
This is the skill of figuring things out through the use of references and thought. It allows you to uncover information that may be key to your work. This can include things such as going through a library looking for books, engaging in experiments to figure something out, or even possibly just assembling the information from your teammates in such a way that new things become obvious. It is also not a bad way for a GM to slip players hints about things their characters should have worked out by now.
