"Wh-what?" Moonstone stammered, as Obsidian helped her up. "What does this door lead to?" she wondered aloud. She stepped up to it, touching the gem that was hers and it glowed. "Is it supposed to open?" she wondered.
"I don't know," Obsidian replied, walking next to Moonstone and touching hers. Both of their gems on the door glowed and the door opened.
They both stepped back, surprised, and the door closed.
"Someone else try it," Obsidian said.
