The question that ignited the powder keg was as many others over time, asked without expecting an answer; "where is the best place for knowledge to be found?" only meant to be clever set up to coax a wrong response out of the interlocutor, the correct (and somewhat pedantic) response was "out there, for we know not one fraction of what it is to know"; but any hope of ever reaching that retort died seconds later when the shouting started.
Scholars, particularly drunk scholars, are opinionated creatures who won't hesitate to educate their peers out of any mistake. So, what started as an interesting discussion in a bar that catered to those of scientific interest, about the nature of knowledge itself; a conversation comprised of a few somewhat tipsy individuals who used their free time chatting whit friends to have fun and polish their rhetoric, soon devolved into a verbal brawl in which each faction defended their alma matter without regard for accuracy or truth and who among them had collectible drank a small vineyard.
The discussion was broken before the first punch was thrown only thanks to the intervention of a nearby dwarf. The bearded menace had invited itself into the conversation without the slightest hint of subtlety by loudly declaring that a library none of them had ever hear about was the richest in empire lore. When asked to elaborate by skeptical scholars the chainmail-clad creature had started his answer whit a disapproving grunt that triggered long-repressed instincts from their time as apprentices, archiving absolute silence and stillness from people who thought themselves masters on their respective fields.
Whit a voice coarse as gravel and yet whit perfect diction told the tale of a library that shared Ghal Maraz's origin, an artifact made by dwarfs to pay a great service done for them by a human; open to all who seek knowledge no matter species or creed, so vast as to hold two empires worth of bibliography in a few subjects yet expertly organized and preserved.
For hours they listened whit rapt attention to tales of not less than a dozen conjoined research projects among dwarfs and men of which this library had been the epicenter of, military campaigns that were saved thanks to information provided by this archive, and of the people who visited the place. From empire nobles to lord magisters, elector counts, and even an emperor dragon had chosen those halls as their preferred option to study and even publish some of their own work. Before the tale was over each one of them had silently vowed to travel to that wondrous place even if it was the last thing they ever did.
Vow they immediately broke after the dwarf started talking about spiders.
