"I wish for a gold coin that doubles every day, in that I have 2 the next day, 4 the day after that, and-"
The urchin noticed that the Genie had frozen, as had the cave around him, in an eerie green light.
Then a portal opened and a small figure in a black suit stepped through with a clipboard and a pair of half-glasses on a chain.
"Hello. You have attempted to cast or invoke a magic spell that will cause an economic collapse within a few months. What are you intending to spend the money on?'
The urchin blinked and rubbed his head.
"Uh... Food? A bed? Wine? Women, maybe some of that-"
"I see, are there any others you intend to support or use the money on?"
The urchin thought about the other urchins.
"No."
The figure nodded and filled out a scroll.
"So no plans for inter-plane interactions nor major political or magical upheavals?"
"No, man, I just want to live a nice life."
The figure nodded as they continued scrawling in gaps on the scroll.
"Very wise. Sign here."
The urchin, confused, signed.
