I purposefully didn't ask Xander anything important regarding his trip to the Eastern Country. Judging just by his arrival, he wanted to be around me constantly which will lead him to tell me all about his trip, so I knew that he would eventually get to any of the important stuff at one point.
From what I have gathered through Xander's stories for the past few days is that the Eastern Country is a whole lot more advanced compared the the Book of Vessels. Like I know that a hundred years is enough time to change significantly, but I wasn't expecting it to change with such intensity. From employee-free grocery stores to robotic bus drivers. Everything is automatized using robots and AI. The people who live there earn money through IT work and security surveillances. There are still human-ran operations like hospitals, farms, and large department stores, but almost 90% of the workforce are robots.
