Maybe we have been thinking about the library too much from a mechanics perspective instead of seeing it from a historical perspective, namely what the great libraries were before the rise of the printing press (which may never be a thing in the land given the requirements to create lorebooks, skillbooks, spellbooks, expertise books and so on) and for centuries after. They were centers of knowledge and more often than not they were sponsored by great lords and kings. There is a great deal of prestige as well as advantages in sponsoring such a place, especially combined with an open society such as Richter's. t could see a core library directly impacting: City mechanics: - Attracts more citizens (may not strictly speaking be a mechanic) - improved morale and loyalty. - improved learning speed and retention - Increased skill gain Diplomacy: - Somewhat Greater regard from nearly anyone depending on their level of interest in knowledge. Very few powers view knowledge as inherently bad even if they believe certain types have to be limited for the greater good. That could be anything from knowledge of stealing souls to the fact that other realms have abolished slavery and instituted the relatively more benign institution of serfdom. Some might even have gone a step further and done away with that institution as well, binding the people to the land but otherwise leaving them free in a legal sense. - Major bonuses to relationships with any knowledge focused powers. - Greater renown and fame for vlillage/Richter. This is the one corebuilding I would tell the rest of the world about because its likely to attract more friends than foes. Research - Greatly increased cap for each tier of research. The scholars hut is focused on the generation of research points, perhaps the library is focused on increasing the amount you can generate. - Almost certainly a limited amount of passive researchpoints. - A miniscule amount of research added for "free" researchers working within the library as long as they have not reached the cap for that rank. Bookmaking - Boosts to the speed with which skill, expertise, lore, spell, etc. books can be made. This will allow for the rapid dissemination of knowledge in the community so within bounds for a center of learning. Indirectly I also think a core library will attract scholars, loremasters, anyone with an interest in knowledge, especially that of other races that normally stay within their own territories. Hard to say to what extent, but as the village grows in renown no doubt it will attract more and more. A soft power approach that doesn't rely on stats, but should nonetheless work. Given the number of mages, a tower or four of magical research would be a nice addon.
