Gesen Bow String is an item found in the Asylum Dungeon. It can be found in the locked chest in the vault in which some inactive golems are standing still, but they will be activated after unlocking the chest. This item appears in Baldur's Gate II: Shadows of Amn. Cromwell can use this item to create the Shortbow of Gesen, if the Gesen Bow Shaft shaft is in the possession of the player character as well.
