The Hidden Secrets

When the Alfar armies were on their way advancing toward Chaldea, some wise citizens of Ashur sensed the danger and they ran away with the help of a teleportation portal to the wasteland continent of Cairn where lay a trading post called Kaskim. They tried their best to transfer as many books and artifacts as they could and finally they became the heir of all learning of Benevolent Empire. In Kasdim, they lead a secluded life for many a century, until their lakes providing fresh water for the city dried due to climate changes. People could not live there any more.
Always bearing in mind their final mission to continue the culture of the once-mighty empire, the last Chaldeans built a well-defended dungeon which was located at the center of Kasdim, and they named it the Halls of learning. All the books and artifacts they retained were hidden in this place. Even with today's technology, none has been able to penetrate into the heart of the dungeon to find the legendary treasure the Chaldean had left.
