Lore sounds promising:
The tale of the maiden voyage of the first ever onslaught
The limmerick of how the hegemony was founded

The romance novel inside out, the story of how a donor kidney got to be the captain of a lasher and savior of the princess from the gravatic jaws of a black hole.
The folk lore of traders: "if u bump ur head getting out of ur bed for watch, double tie ur shoe laces to stop bad luck", "masturbating out of an airlock is how super novas happen", "washing ur ship with space worm excrement blocks patrol scans", "a voltan crab shell under ur pillow will stop alien abductions", etc.
The bermuda triangle of space?
