The Dark Spirit Race built countless Veil Spirit Gates across the universe over the long years of the past.
They were everywhere.
Even near Holy Terra.
Perhaps they wouldn't dare to send raiding parties to directly operate near Holy Terra. Even during the decline of the Human Empire, with Holy Terra as the core of the Empire, it always retained its strength.
Every bit of force from the Dark Spirit Race was precious, not to be wasted casually. They always assessed the risk-to-reward ratio.
Raiding near Holy Terra was not only difficult due to strong defenses but also, once exposed, would draw strong counterattacks from the Human Empire, making it unwise.
However, this place was extremely important. Holy Terra was the core of the Human Empire, with an abundance of information. Upon hearing news of a transport fleet operating outside the core region, they could transmit the information back and then organize a raid to seize the goods in a relatively safe area.
