Legendary War

I continued playing, and the map is about 30% explored. I found the Tear of Ashera, and that's it! The game ended. Basically, if the task is to find the Tear of Ashera and defeat everyone, then both tasks need to be completed. Otherwise, the game ends immediately. I didn't find the Mentor, although it's mentioned that he's on the island, and I cleared the entire central island without finding him.
