Lisa and Kyri joined the Freebooters on their flying ship, traveling to faraway lands. On this particular occasion, Lisa had been abducted by a djinn who took a fancy to her.
The djinn shifted into the Etheral plane, where he trapped Lisa in a floating rock for later retrieval.
The capricious djinn showed no signs of returning, and Lisa had to deal with the situation herself. Using her recently awakened magical abilities, Lisa realized she could move through the ether with the power of her mind.
Focusing on her chosen destination, the Freebooters' airship, she eventually ended up in her own world. Unfortunately, the stone into which she was inserted arrived with her. The flying ship was indeed nearby, but far up in the sky, moving away.
And then there was this hot, but scary-looking woman asking questions in an unknown language and waving a magic wand in annoyance.
