Frame of Reference is an aspect of Learning and Knowledge used to describe an character’s personal experience of what they know of as possible and/or probable given their current technological and cultural advancement in their Setting, and/or what might have been covered under training/education. Knowledge and skills are most useful within an individual’s known frame of reference. Any attempt of an action or applying their knowledge outside of this may suffer a penalty or not be possible altogether.
ADD:
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. With a common frame of reference, multiple specific Lores can stack.
