“Legend had it that in the deepest part of the oldest galaxy, there was a door as red as blood and fire.

Legends and myths, darkness and light, countless stories passed through this old door.

The Door of Constellation that overlooked everything would warn the sky and earth, sending darkness back to where it belonged.”
