The cleric was pushed back and prone underneath where the dragon was flying; she just didn't have time to stand up yet

… while also pushing the gemstone into the bag of holding with her sword. I know my character and myself around pretty gemstones

She was not actually going to *touch* the gemstone that was absorbing light. At most, she was going to coo at it going, “oh, you’re so pretty! And so magical! You get to stay there.”
Sincerely, the Cleric
