First Rein wanted to find a library to learn more about this world. Especially about the history and geography. So he went out to find a library with Colinde. But he was disappointed soon afterwards. That was because Rein found out that there was no library present at least in this region.
Knowledge was judged to be very precious and the big clans and sects had a monopoly over them. The only way for common people to find books was by buying it from rare book stores. But the cost of a book was insanely high and normal people could not afford them.
So if Rein wanted to read books, first he needed to earn money. Without it his options were very limited. So for the time being he gave up on the idea of reading books and started to plan about how he should test his and Colinde's skills out.
