Fictional

Mordred felt slightly panicked. 

Obviously, this wasn't because she feared Nile's strength. Whether it be by her own opinion or by the fact of reality, the truth was that there were very few on the current Earth that could match Mordred in power. 

The issue was that this wasn't a situation she could brute force her way out of. Even if she easily deflected the advancement of these wolf riders, what would she do about the thousand strong army to their back? And even if they somehow managed to repel them, what would happen to the situation with White City if they suddenly began to infight?

Even though The Empire seemed to be helping now, Mordred and Arthur alike were very much aware that Camelot wasn't their home ground. The Empire could easily choose to retreat and focus on Earth and come back. 

But could they do the same? They could technically find a place on Earth, but what could their millions of citizens do? Where would they place them?
