Our current RP runs much on that thing we call "plausible canon" anything that isn't defined in lore must be plausibly derived out of it. The setting itself is a hole in the timeline of the Star Wars extended universe. A hole with clearly defined edges but no distinct filling. 

Even with the established lore, one has to consider everything. There's so much lore in the Extended Universe of Star Wars that not everything can be reliable, or at times even plausible. With hundreds, if not thousands, of authors you will have some that stretch things beyond plausible. anyways, we think the point is clear enough.

Not that any RP is truly 100% Canon, seeing how a 100% canon story would be a copy of an existing story.
