It wasn't surprising that Bangyan had heard of the Teizene Civilization; after all, the Galaxy, spanning 60,000 light-years in radius, wasn't particularly vast, especially for a group of High-Level Civilizations that had breached the second-level warp speed, crossing the Galaxy in just over thirty years.
The High-Level Civilizations performed activities across the entire Galaxy, and some even ventured into extragalactic star systems. Intermediate Civilizations, ranked between levels 15 and 25, generally operated within a 2000 light-year radius. The position of the Danlu Interstellar Bubble, where they presently were, was also within Teizene's activity range. Although Teizene themselves had seldom visited this spot, other civilizations would spread the formidable reputation of the Cannibalistic Civilization.
