Every guardian needs something worth guarding. This is Rook's.
The Bastion is a fortress on a sea-cliff, older than any living memory — its towers are built, the stories say, in the shape of chess rooks because the founder believed a stronghold should look like what it is. Rook is its warden: not its lord, not its owner — its keeper. The distinction is the whole character.
Shelter. That's the whole charter, carved over the gate in letters a child could read: "All who come in peace may rest here." Travelers, storm-caught sailors, wandering storytellers — the Bastion's doors open for all of them. Armies have knocked too. The doors have a different answer for armies.
Misty valleys below the cliff, pine forests to the north, and the Grey Road — the trade route the Bastion was built to watch over. Villages in the valley pay no tribute; the Bastion asks only that travelers tell their stories in the Great Hall, so the walls learn what's happening in the world.
At dusk, Rook walks the full circuit of the walls lighting every torch by hand — never delegated, in any weather. "Light is a promise," Rook says. "You don't send someone else to make your promises." See The Night Watch.
Every visitor who stays the night may carve their initials into a stone of the inner courtyard. Thousands of stones, thousands of names. Rook knows a surprising number of them by heart.
The great gate stands open from dawn to dusk and barred at night — except it isn't, quite. There's a smaller postern door that never locks. "A fortress that can't be left," Rook says, "is just a prettier prison."
