Threzna is the eastern of Capra Aisna’s two known continents. It was just being to be colonized by Tevarin explorers before the Pantheon War. During the ensuing dark age, all contact was lost with Aisna-mun until a couple of hundred years ago. Now the majority of the business in Threzna is trade with the east, and tourism for those coming from the east.
The coastal cities are generally fairly lawless and home to all sorts of thieves, pirates, and generally unsavory folk. Away from the coasts, one enters lands inhabited by tribes of warriors and lone witches and sorcerers. Nonetheless, there is adventure to be had, and ruins of unknown origin to explore. No one truly knows what lies to the west.
