The Reians are very experienced with where the Balaur holds are, but they simply don't have the forces to dedicate to multiple assaults.

Among them, Hariken is the one who found the Aturam Sky Fortress, where Tiamat's airborne troops are stationed. Unfortunately, Hariken has become trapped and unable to leave the Fortress.

The Balaur's Dredgion technology is something we must acquire at all costs. You can learn how to get there from Nimrod. You have all the information you need. Move!

I'm not entirely sure. I've never been able to pinpoint his location. The only relevant information I have for you is about the Kaichin Engineering Union.

The Kaichin Engineering Union is made up of Shulacks and they have superb airborne technology. They seem to be in league with the Balaur.

Sounds like something to look in to, but I'm really only able to help with travel to the Sky Fortress.
