Help with a title for my fanfic

[Forlong 1,726]

I'm getting together a fanfic that I hope to release starting in June, if I can get prereaders.  However, I can't decide on a title for it.

 

Summary

Long has Equestria held back the forces of darkness.  Changelings, Brollachans, Leucrottas, Chimeras, and other evils to despicable to speak of.  For a time, they have been able to contain these threats when they came about one at a time.  But no longer.

King Sombra has allied himself with Queen Chrysalis and turned Prince Grogar to the dark side.  With Grogar's aid, they have gained access to Tartarus and every evil creature within it.  Even with the aid of the Griffins, Zebras, Goats, and Minotaurs; will Equestria be able to hold back the darkness?

 

I'm torn between these two titles:

• The Changeling War
• Grand Equestrian Millitary: GEMs

Changelings: The Last War
