Silver raindrops, golden clouds

Sombra sat in the library, reading his new favorite book. He loved to stroke the soft, leathery green cover as he learned about the secrets of magic. Unbeknownst to him, this was an enchanted book, one that was possessed with a strong dark magic. The book would be an abhorrent object even without this quality, as it was bound in pony skin. The longer he read it, the more it corrupted his mind, turning him against those who loved him the most. He was not at all surprised to hear the sound of a portal opening and closing behind him. He turned around to see Ahuizotl standing behind him. He stood up before him, not at all intimidated by the demon's size. He looked him straight in the face.

"Have the documents been retrieved?" Sombra asked.

"Yes, my lord" Ahuizotl replied, smiling.

"And the mare has been set up?" Sombra inquired, giving Ahuizotl a piercing stare.

"Of course, my lord. She doesn't even know that she stole the documents, but the guard certainly does. I personally saw her kill three of them with a candlestick." He replied, chuckling slightly at the memory.

"Pregnant mares are always the strongest." Sombra said, smirking slightly himself. Soon, the mare would be put on trial and executed. The loss of his only friend would destroy Gold Soul, his big brother. If his brother didn't kill himself or leave the kingdom from the heartache, Sombra would have him assassinated personally. After that, there would be nothing between him and the throne of Equestria. Sombra smiled.

"Very good, Ahuizotl. You may leave now." He said, musing over what he would do as king. Ahuizotl smiled back, and vanished in an instant into his portal.
