We learned that he is very lonely and isolated from the world.
Explanation:
When reading the short story, we can see that the narrator has the hobby of reading old books that portray the world outside the castle where he lives. This demonstration of the world outside the castle is the way the author travels, as he lives completely alone and does not know anything about the world, other than what the books present.
This shows how the narrator is lonely, inexperienced and a little sad for the way he lives.
