Proposed Canon
Short Pier is a location in the east side of the Magic Kingdom. When a barbarian caster is unable to pay their upkeep, they take the Long Walk. They wait here for their final sunset before they disband. If they are very lucky, a generous caster might offer to give them a Rand to live another turn. Almost every day, some caster waits here to meet their Fate. Often even more than one.
