Eyghon, Fortress of the Earth (1)

"Eyghon?! Why has it appeared?!"

At that moment, it wasn't just Jin and Ysabelle who felt fear coursing through their veins. Even Capella Moonreaver, the mighty Asterias that served as the spear of the Moonreaver House, couldn't help but grimace. Her shock was so extreme that she had forgotten her duty as a bodyguard, completely ignoring the blonde-haired girl she was supposed to protect by not bringing her to safety immediately.

But Lilith didn't mind. Rather, her eyes bulged out in fear as she added:

"Eyghon?! Is that Outer Demon really Eyghon?! The Demon Lord?!"

"There's no doubt about it!!!"

Capella yelled, not bothering in the slightest to hide her anxiety.

Very little is known about the Outer Demons. Why did they decide to invade the planet? How did they manage to create ruptures in Spacetime to connect the two worlds together? And why haven't they launched a full-on attack to destroy humanity?
