Falen knows that the construction of the Great Gate Construct included not only steam gnomes, but also the Wizard Council of Bluffside. Dwarves were also pivotal in its creation and eventual integration into the Iron Gate. It is true that a version of the construct once stood in the Grand Gallery but, the construct that exists now in the Old City Rift isn't the exact same creation that once stood proudly in front of the Palace of Bluffside. The original Palace Construct was almost completely destroyed during the siege and pieces of it were repurposed to create the Great Gate Construct. The Palace Construct was created around the same time that the construction of Old City was completedKnightfall said:"The Great Gate Construct was built generations ago by the steam gnomes. At first, it was merely a curiosity and barely moved at all. Over time, the gnomes and the Wizard Council enhanced it to be able to perform more complex movements. It used to stand in the center of The Grand Gallery in front of the Palace. It was moved into the Old City Rift for maintenance and never came out again. Morlocks tried to invade Bluffside through the rift and after they were repelled, the Construct was repurposed to stand guard near the top of the rift and open the Iron Gate."
