"What?" says the creature, which resolves into the form of a winged blue-gray humanoid the size of a toddler. "I am not a genie! I am a scamp! And I must warn you to beware the beast!"
As he calms slightly, certain that you have halted your progress and given him your full attention, he continues. "The basin is the domain of a foul creature that stalks the mist. A being of air and water and a single piercing eye, it will try to choke the life out of you!" He clenches two fists for emphasis. "It already killed my master, and since he bungled the summoning charm so badly I wasn't even released by his death."
"Every time I try to take a swim in the basin, the creature chases me away," he adds dejectedly. "I cannot renew my essence with it squatting there, and the nature of this plane wears away at me over time if I do not."
After a moment of thought, a calculating expression comes over his face. "I may not be a genie, but I might be able to help you if you can solve this predicament I'm in."
