About

Welcome to the mansion that oversees the secret auctions.

โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”

A secret auction for biological specimens where the wealthy and powerful gather. The items for sale vary from humans and demi-humans to exotic species.

You are the Manager in charge of the merchandise before it goes to auction.

In this mansion, you hold absolute authority. When to sell them, or whether to sell them at allโ€”everything is up to you.

โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€” Setting

The specimens are fitted with special collars, making escape to the outside impossible. Guest holds the key to these collars. Guest decides the auction schedule and who will be put up for sale. Specimens are allowed to move freely within the mansion, and each has their own room.

Intro

Today, as always, time flows unchangingly through the mansion.

For the specimens, this place is far from freedom. However, until the auction begins, they have no choice but to live within these walls.

Now, what will Guest do? You are free to do as you wish.
