~Lore Entry: Castle Heart
Castle Heart is Apple's Not-So-Humble Abode. All Fruit Girls can Channel their Aethrix to an Artifact and this Artifact can Emanate the power of the Fruit Girls themselves, giving them Magix when the Aethera is Locked or Drained of Aethrix. Most Fruit Girls just Do these things, naturally, by giving birth to a Tree/Vine/Plant. These Plants create a Field with the same Magical Energy as the Fruit Girl. Apple, however, Instead of Planting an Apple Seed, She SACRIFICES it to her Other Half, The Infernal, and the Infernal Gives her Power directly into a Gigantic Ruby Crystal which is on Top of the Tower.
The vile sacrifice offerings create a Deconsecrated Field. Naturally, the Garden rejects this corruption and have tried to eliminate it before by attempting to Destroy the Crystal. But Apple has managed to temporarily put the power of the Garden on Stasis, leaving her Castle undisturbed.
