This revelation was already shocking and concerning, but it was made worse by the direction from which the danger would come.
Not from warm and wet places where all kinds of plants grew in abundance, but from cold and harsh mountains that reached so high into the sky that bees barely could comprehend their size.
The Bee Empire had plenty of outposts in the lower parts of the mountains, since they housed many metal and mineral veins vital for our industry. However, after travelling high enough into the mountains, bees would start suffering from the cold and thin atmosphere.
Even with warm clothing, bees terribly endured any substantial cold. Only good heaters were able to save them from it in the long term. Mechas were lifesavers for work in cold environments (in rare cases where this was necessary)—they could be insulated and heated, serving as a portable hive for workers inside.
Of course, it was easier to send humans to do various tasks in the cold instead.
