Mihale Maztaim was laying on the ground, with, of all things, a large blue dragon towering over him. Something thudded the ground behind her. She turned in Jessica's arms to see a smaller dragon with prominent human breasts and brown scales step up to her.

"Are the rest of you here?" Shelly asked. She wanted to embrace her sister also, but Jessica didn't show any signs of letting go.
