A gate warrant is a sort of passport allowing passage in or out of Graceport. All gate warrants are required to be authorized by Queen Regina or one of her ministers and bear the seal and signature of their issuer.
There are two types of gate warrants: a “Restricted” warrant is valid only for a certain period of time—usually a single day. A “Free” warrant is valid in perpetuity, allowing the bearer to come and go as he or she pleases. These last are exceedingly rare and use of a “Free” warrant has been known to draw attention by the Gate Watchmen, and subsequently, nearby bystanders.
Possession of a forged gate warrant is a capital offense, though some forgeries continually surface.
