Great Gerabervia War

"The Great Gerabervia War? What the heck? Nadia Silbergeld is so super ruthless that Trixie Lulamoon told me about the death of Emperor Silbergeld, his foals and Princess Celestia would be much worse than the Great Crystal War. You see, that alternate timeline does reminds me of Queen Chrysalis' own world where she finally took over almost all of Equestria while the Everfree Forest is the last bastion remaining."

--Su Ji-Hoon, The Great and Powerful prophecy

The Great Gerabervia War is a alternative war waged between Equestria and the Empire of Gerasecia in an alternate future timeline of USRAC War created by the entire of Global Liberation Union. It is featured and mentioned in Trixie's prophecy.
