Well, there are these heroes who are a core part in the story called "The 7 great knights" and this is where they are now. The leader is dea because he sacrificed himself and you fight him as a secret final boss, one of them retired and became a mage, one got corrupted by darkness and basically became a zombie, one guards one of the keys you get, and 3 of them are still doing what they've always been doing.
Why do I bring this up, well one of the knights, the dragon tamer, reveals that he works for the main antagonist and kills 2 of the knights, the twins. Except I doubt you'll remember this by the time I make the game.
