You have been selected. The criteria are opaque, the selection irreversible. What arrives is not a letter but a shift in perception -- the sudden awareness that beneath every handshake lies a handshake protocol, beneath every smile a cipher suite.
The Masquerade does not begin when you put on the mask. It begins when you realize you were already wearing one.
Before you enter, you must become unreadable. The protocol strips away legibility -- your name, your face, your intentions are run through rounds of substitution and permutation until only the mask remains.
This is not hiding. This is transformation. The plaintext self is archived; the ciphertext self steps forward. In the ballroom, no one decrypts without consent.
The ballroom is a network topology made manifest. Every dancer is a node; every exchange of glances, a packet. The chandeliers are routing tables. The orchestra plays in frequencies that carry metadata.
Here, masked figures negotiate in the language of gesture and proximity. Alliances form and dissolve like ephemeral connections -- stateless, sessionless, beautiful in their transience.
The protocol's final phase is voluntary vulnerability. When midnight strikes, the masks do not fall -- they are offered. To unmask is to transmit in cleartext, to open a port, to say: this is the face behind the face.
But here is the secret the protocol guards most fiercely: there is no face behind the mask. There is only another mask, more beautiful and more honest than the last. The masquerade never ends. It only deepens.
