Lord Dawn's Tea Party

From the introduction:

The players received an envelope in the mail, which contained the rules of the game, their character sheet, notes on practical aspects (like a small fee), and any documents or small objects which the character should have at the game - in other words, all the OOC stuff. Also inside this 'player' envelope was another, smaller ornate envelope, addressed to the character and sealed with wax. Inside this smaller character envelope was the invitation to Lord Dawn's Tea Party.
