Remember
the tallest mountain of 40d?...
Behold,
Project Coppertop, a pyramid of 43 Z-levels in height, which is soon to be cherrfully painted - as per the fort's name and modus operandi.
This shall be accomplished through the works of Project Awesomedrop and its frightening altitude, made out of alunite, solid gold, rose gold and red glass, along with an internal structure of golden bridges and a careful placement of mechanisms.
Underneath the pyramid is a glorious superstructure housing all the dwarven inner quarters, workshops, dining hall and artifact vault, along with the noble quarters and the mayor and manager's rooms. The bottom-most floor has been flooded with magma, helping fuel the forge equipment.
To defend these noble projects, two squads of elite champions were created, headed by the squad leaders Randy Savage and Bear Force One, both of whom fell in glorious battle after having respectively amassed 198 and 111 kills. Replacing them and fighting in their memory is Firetruck2meetu, standing tall at 60 kills, still guarding the project to this day with his bretheren, constantly training such that no megabeast can enter the premises without their express permission. Of course, all humans and goblins are captured, stripped naked, cavity-searched and then dropped onto a mysterious platform, awaiting their fate.
A small pack of dwarves have moved to the very top of the project to inaugurate it at last, after 64 years of tireless building, fighting, smoothing and engraving. Their targets: the yellow switch on the right, and the bottom-most black switch on the left.
You know what to do.
