I kinda knew they had some sort of weapon, but I thought it would have been one where it was created for the good guys to use as some type of last resort/thing we had to make because it was a dire situation thing.
But the fact the First Ones build the Heart of Etheria and wanted to use it on their "enemies" without caring about the collateral damage, was the thing that startled me. >I figured out what my people are doing with the Heart of Etheria. What they've done to the planet.>It's going to activate soon, there's no time.> It's starting.>I can't stop it. But I can keep them from hurting anyone else.
MA: She-Ra's destiny was to be a part of your machine. But I won't ever let you use her again.>LH: The Heart of Etheria has been activated. Your mission will be fulfilled. There will be peace throughout the galaxy. You will be a hero.>MA: How will destroying worlds bring peace?
MA: Didn't know what they were doing until too late. I knew they were rerouting Etheria's magic for their own purposes. Siphoning it, collecting it in the planet's core.
The Heart of Etheria. The Heart of Etheria Project.It
was supposed to be an energy source, capable of so much good. But that's not what they made. My people turned our planet, all of Etheria, into a weapon. And She-Ra is the key.
I opened a portal to a completely empty dimension and pulled Etheria in. I hid us from the rest of the universe to keep everyone safe. This is the one place they'll never find us.
The weapon can't hurt anyone else here. I saw what they would do. The deaths that would follow. I couldn't stop them before, but I can now.
From the sounds of it, the Heart was used before on some planet and deaths followed and I'm wondering if Horde Prime's planet may have been the first casualty?
