Its story
This magic weapon can take the form of any melee or ranged weapon. Its grip, haft, or hilt is wrapped in weather-darkened climbing cord, with a small brass anchor fixed close to the hand. A thin blue line runs through the metal like a route inked onto a survey map. When its bearer strikes a foe who has hurt a companion, the line flares blue and the weapon gives a taut, rope-like twang, felt in the palm as much as heard.
Lore
Among Anemora's climbers, a life saved on a failing route is not a kindness to be tallied and forgotten. It is a line left tied between two people. The Climb I Owe is said to remember that line, answering most fiercely when its bearer turns a rescue into action and stands between a companion and the next fall.
History
The weapon's earliest known bearer was a survivor of a failed ascent who never forgot the person who held the line long enough to pull them from the dark. Later copies and awakenings have been associated with rescues in the Sound-Stone Quarry and on Linden Cay, where Isolt Fenwick's peril became a story of debts repaid at personal cost.
