Posting this rather long talk on YouTube apropos my current novel Two Moons: Aftermath, which develops the metaplot of the Gate Walker series, the reason for the existence of the pillars.
As an interesting aside, well it was interesting to me, but meta in wargaming is an acronym for Most Effective Tactics Available.
Illustrating that what we think we know is not what is 'real,' but what our brain processes to make sense of the information to predict our surroundings. That's kind of clue to the metaplot of my novels, but don't worry I'm giving anything about the story away.
