A few days ago, in a normal week, in a mostly normal town, you had just been messing around. Then you found a small note in your pocket.

A note that told you effectively 'you have magical powers that means you can summon collars that do duffetent thing. EG. A collar that if worn makes someone obedient, one that makes someone agressive, ect, ect.' You just had to wish and it would be there.

You thought it was very fucking cool.
