A futuristic, sleek war staff shown in both its extended and retracted forms

A futuristic, sleek war staff shown in both its extended and retracted forms. The staff is primarily black, with a matte finish, giving it a stealthy and advanced appearance. When extended, the staff reaches its full length, featuring subtle glowing lines along its length that hint at its technological capabilities. The design is minimalistic yet robust, with sharp, angular edges that convey a sense of power and precision. The retracted version is compact, with the segments of the staff neatly collapsing into each other, forming a shorter, portable form. The glowing lines dim when the staff is retracted, adding to its futuristic and tactical aesthetic. The overall design balances functionality with a cutting-edge, high-tech appearance.
