Griffith was imprisoned in the Regeneration Tower Prison in Wyndham City. When the Eagles went deep into the dungeon to rescue him, they talked about it. This place was the site of the Overlord era thousands of years ago. According to legend, the Overlord was a powerful knight wearing a skull mask. He unified the continent with force, but was eventually judged by heaven for his unkind acts. Four or five angels descended and destroyed the Overlord's kingdom.
