Technology

Many parts of Mindosza used to be quite technologically advanced before the Convergence. Some of that knowledge was used to build and survive in the Havens , however most of it was lost to the ages. As time passed, most recordings of past achievements withered away or got buried. Most survivors were busy tending to their lives in their shelters. Now, that the gates have opened and the land is ready to be reclaimed, so is some of this ancient knowledge.
Examples:
Airships
Railway
