This time period covers the events around the establishment of the Hunters' Guild known as The Archaistic Library, everything that went directly into its establishment and its growth in the environment thereafter. These are ancient times before any unified timekeeping therefore how time is denoted depends mainly on whatever large civilizations that were established an grew enough to maintain a relatively large population were local to those recording the events of history. As a result, different sources track time different ways and putting together a timeline of events may take some homework and study.
Central to the establishment of The Archaistic Library is Amari Elder, its eventual founder and leader, though naturally the events that would get them to that point were set in motion long before they were born. The world at this time is a largely untamed frontier populated by many creatures both benign and exceptionally dangerous. Despite this largely hostile environment, humanity's incredible tenacity and resilience has led more than a few groups to establish pockets of civilizations, from the numerous villages dotting everywhere you could imagine to a few well established cities. In order to protect the smaller settlements from the dangerous fauna that rule the land, people band together in Guilds that travel from village to village helping with the day-to-day tasks and, more importantly, defend the villages from any major threats in the area. Due to the abundant amounts of dangerous fauna and the fact these adventurers seek them out, they're often referred to as “Hunters”, giving birth to the guild type “Hunters' Guild”.
