Mid Tower
From Halopedia, the Halo wiki
The Mid Tower was a Covenant tower on the orbital city High Charity. It was sandwiched between Hanging Gardens A and Hanging Gardens B. Towards the side closer to the Forerunner ship, it featured a multi-leveled Gravity Lift. The Covenant Separatists, namely, the Elites, Grunts and even several Rangers, fought with the Jackals, Drones and Brutes of the Covenant Loyalists for control of the Mid Tower, but were all slain by the Master Chief.
