Whispers of Tirathis
From Loranon
Salamat, Fretista, Euramer: all of these were great civilizations that were known to exist before the rise of Marco the Enslaver. We know much of their history, culture, and fall.
Dranor, Kalastan, and Shudicali: all of these are lesser known civilizations but at least we know roughly where they existed and discoveries into their past still occur.
There is one civilization that Marco strived to wipe out above all others. All that remains are but whispers of Tirathis. We know more about the secretive and hated-by-Marco Diran people than we do of those from Tirathis. Even its location is lost to time.
