Like the other secret citadels, Harbone was established after the murder of King Jupiter, with Lord Hews as its first lord. Following the third Citadel Congress, Harbone-the closest citadel to First Warren-volunteered to undertake preparations for the eventual Retaking of First Warren. Harbone's archers gained a particular reputation for their excellence, with only the Bracers of Halfwind Citadel rivaling their abilities.
Wilfred Longtreader makes a brief visit to Harbone prior to the Citadel Congress at Cloud Mountain. He reports to Smalls that Harbone's residents fear that their destruction is imminent, and further reports that they lack trust in him due to his association with Garten Longtreader.
The prowess of the Harbone archers is touched upon by both Nate Flynn and Clay Fletcher. An embassy from Harbone attends the Cloud Mountain congress, and the soldiers participate in the Battle for Cloud Mountain, with one archer firing a shot that saves Jo Shanks from a wolf.
In preparation for the Siege of First Warren, the most vulnerable citizens of First Warren are evacuated to Harbone Citadel. Unfortunately, while Wilfred is leading the last evacuees there, the citadel is attacked by the forces of Longtreader Command, several Lords of Prey, and the remains of the Wild Wolf Pack. The citadel is left a ruin, and many rabbits are slain, though the arrival of the Fowlers and Wilfred prevents a total massacre. The survivors return to First Warren, where news of the attack proves particularly motivating to the surviving soldiers of Harbone as they prepare for the end of the War for All Natalia.
