The Red Fortress of Star Antimony was a palace built by the "Red Chancellor" deep in the mountains during the early days of the nation's founding.
It is called the "Red Fortress", but it is actually not red in color.
On one hand, this is because a large amount of gold was used in its construction. When the sun sets, the not yet darkened sky would reflect off the golden palace, making it as red as fire.
On the other hand, it's because the "Red Chancellor", long believed dead by the people of Star Antimony, is actually an immortal Son of the Moon. The palace itself serves as his eternal pleasure garden for indulgence.
Although officially, the Red Chancellor has been uninvolved in politics for many years.
Yet, the wealth and connections he amassed over his long life have become sufficient to operate and appreciate in value on their own. Therefore, he could enjoy his days and nights in the Red Fortress without any need for power.
