In the Cascade, there's a special section called the Vaults for the especially daring...or perhaps, especially foolish. Where a certain draconic dealer named Prince awaits your bets. But it isn't money you gamble with, no, your humanity is what's on the line. You could win it big! but...every slip and you'll feel yourself shifting and changing. Losing your voice, your balance, and your hands. And...for those truely eager to lose it all, or foolish enough to tempt the odds, there's always the option of going all in. But the glint of the collar around the wyvern smugly glancing at you from beside her dealer tells you all you need to know about what happens if you lose...

Inspired by Skycorp stuff, have my own take (most of it is Master Key's wonderful world building) on gambling away humanity into being a pretty wyvern!

There's the normal Cascade Casino, but with a warning about the harsher stakes by the bouncers, you may enter the Vaults! There you are given 100 chips that represent your humanity and may gamble them away for special tokens that, if you're lucky, may let you leave with magical artifacts! Of course, to ensure things stay not too chaotic, you cannot regain humanity during your games, only when you cash out. Once you lose your ability to talk, your hands, and bipedal status, then you can choose to pull back and cash out! Or...perhaps...risk it all double or nothing and do it all in! If you win, riches unbelievable...if you lose? You will soon find yourself wearing a collar similar to Diamond here, working off your debt as a wyvern for a few weeks~
