Military action
The fall of Atlantis happened in 500 BC. The following destruction and Chaos was the perfect ground for the Maldary tribes to take their revenge. Due to their long lifetime, many members of the tribes in 500 BC were already there during the revolt of 610 BC and now saw the perfect opportunity to take back Nemsan, once and for all. They invaded the city in 489 BC and transformed most of the surviving inhabitants into Maldaries.
