Lightning felt the same. After a moment of walking, they found even more ponies rtapped in crystals. I there was Crystal also. "Allright everypony, time to work!" Shining armor said as al lthe guards started working on freeing the trapped ponies.
"Fortunately, I think we had freed a lot of the ponies now." He said looking around. "We should keep moving forward." Shining Armor said.
Lightning nodded and followed them also, walking beside Sapphire. Everypony else exited the cave and went to the crystal empire.
Lightning nodded. "Be ready for anything." Shining armor said as he and the guards got ready to fight. Lightning did the same, walking near Sapphire and Emerald to protect them.
After a moment they arrived to the end of the cave. In there, Luna, Celestia and Darky were trapped inside crystals also. Just as the las time, their alicorn magic was being drained by the crystals.
"We need to free them!" Shining armor said, but as he said that, some crystal creatures the someones as before, appeared. Shining armor and the guards started attacking them. "You free the princesses!" Shining armor said to Sapphire, Emerald and Lightning.
