The Battle of Bright Moon
She-Ra, Glimmer, Bow, and Swift Wind go to Bright Moon.
Entrapta and Catra are very excited about how things are progressing. Entrapta explains that her contraption that is hooked to the Black Garnet is sucking energy from the other rune stones. It is making them weaker. Catra decides that now is the time to attack and the place to strike is Bright Moon.
She-Ra isn't sure what to do. She has some idea about what's going on. The Horde army is spotted heading for Bright Moon. Glimmer leads her friends to her armory. She's been keeping it a secret from everyone, except her mother who seems to know everything. They don't have much time to get ready before the Horde arrives.
