Knowledge of a locale (system, world, nation, city, village, etc.) geography and travel means, processes, practitioners, places, and implements relevant to the setting; No deep understanding is necessarily implied, without related capabilities/powers. The Common Knowledge gained by any competent skill practitioner can easily be gained by questions and study of recorded information. The Lore Knowledge Levels follow the standard Learning levels.
The broader the scope, the more diffused the knowledge. Knowing specifics of a smaller scope place with a larger cope Lore may increase the target challenge; Conversely, having very specific scoped Lore may lower it.
Frame of Reference: All Skills are bound by the character's Setting (physics), and the details that their culture/society's Science (gathered by Technology), direct experience, and/or collective Records are capable of revealing. A character may not be able to apply their full measure on a different world, with different species and tools.
Common Requirements: Significant time to acquire/achieve outside of Character Inception.
i20™ Making Checks: In going with the "Rule of Averages", only a single Result Check is made to determine Success or Failure and degree/quality of either of an Activity. The GM will { } Narrate it, and/or you may petition for an appropriate impact when anything other than a basic outcome is indicated. Note that checks made without proficiency can only apply a Attribute bonus no greater than the character's Proficiency Bonus.
