The Lake of Lusor (right) on a map of Qo'noS. (2256)
The Lake of Lusor was a lake located in the northern hemisphere of Qo'noS, the Klingon homeworld, near the Kri'stak volcano. (DIS: "The War Without, The War Within"; TNG: "Rightful Heir")
According to Klingon religion, after plunging a lock of his hair into a river of lava from the volcano's summit, Kahless the Unforgettable forged the Sword of Kahless, the first bat'leth, by cooling and twisting the sword in the Lake of Lusor. (TNG: "Rightful Heir")
