The Ranalites are late to the party. Many factors caused this. The cave was not in a place people care about or explore, there were many other important things to prioritize, and no time to listen to Shamans (lit. “people with good intuition despite lack of Specialization”). Also, turns out Ranalite is far worse than most other worlds at dimensional engineering.
They are embarrassed acknowledge-the-unfortunate-results-of-usually-optimal-actions (three syllables).
The interworld contact is of course incredibly important, possibly the most important thing to ever happen, everyone now scrambles to find the most efficient actions for solving the most important problems.
But there was also a group already working on systematizing and sharing fiction. And “sharing fiction” is also a known trend of action between worlds. Also the Shamans say this could be especially important, for some reason.
So here are Ranalite books!
With explanations to bridge the cultural differences. Prioritizing more information (and meta-information) that could be redundant, rather than less information that could be lacking. As is the default approach to information in Ranalite (though not universal. Nothing is universal).
