Lanarian scientists develop a primitive sonar system. Ships finally have hope of avoiding grekks in the low latitudes instead of blindly sailing into them. The cultural impact of this invention cannot be overstated, as scientists, explorers, land developers, shipbuilders, traders, and entrepreneurs became the most influential figures in society. The nobility that had lorded over the commoners for countless generations found itself having to adapt quickly to retain any kind of power. The resulting shift led to the common tongue of Lanarish becoming the most widely-spoken language in the Empire, instead of the ancient Melzeen favored by the nobles.
