One Passport lets you move to another kingdom.
How it works
1. Open /kingdom migrate on your kingdom and apply to a kingdom that has a King and free slots.
2. Its King reviews your application (and your gear) and accepts or declines it.
3. If you are accepted, you get a mail with [Accept] and [Decline] on every server you join.
Accepting uses the Passport, moves your slot and sends you to your new kingdom.
If the kingdom is full by then, you get your Passport back.
Before you move: give up or delete any land you own in your current kingdom. A King can't move.
Your Passport shows up in /balance (Passports) within a minute if you are online, or the next time you join.
Passports can't be traded or sold.
You can also get one in game: one Passport every 120 days for $500,000 (/kingdom passport buy).
