"Why do they want this place so bad? Besides the chance to take me out of the fight, of course."
— Reidak, Legacy of Evil
|Location||West of Destral|
Some time after its construction, the fortress was captured by the Dark Hunters. During the Dark Hunter/Brotherhood of Makuta War, Zaktan traded information with Roodaka in return for details of the fortress. The Dark Hunter then searched the fortress again, discovering a chamber in which Teridax's plan was inscribed onto the walls. After reading and understanding the plan, Zaktan destroyed the inscriptions. The fortress was attacked by the Brotherhood soon after. The Hunters attempted to defend it, but Zaktan, Thok, and Reidak soon realized it was a futile effort, and abandoned the fortress. It was soon re-captured by the Brotherhood.
Over 1,250 years later, freed from his watery prison of the Pit, Pridak attacked the fortress, which had been covered with a new one on top. During the attack, Pridak stumbled across the destroyed chamber, and reassembled the broken pieces. From the writings, Pridak learned how Teridax had struck down Mata Nui with a virus. After Teridax's takeover, Pridak struck a deal with the Shadowed One to mimic this effort with the viruses found by the Shadowed One, but these plans never came to fruition.
The Plan Room
The Plan room is a concealed room within the fortress. Makuta Teridax used the room to record all the details of his plan. Before it was taken by the Dark Hunters, Teridax shuffled the writing and symbols on the wall, scrambling the message so it would appear as meaningless gibberish if anyone were to stumble upon the room.
Some time later, Zaktan encountered the room after learning of the fortress' true nature from Roodaka. Though he was at first unable to read it, Zaktan accidentally triggered a switch in the form of a symbol that rearranged the writing back to normal. After studying it and committing it to memory, Zaktan destroyed the wall.
Much later, Pridak discovered the room during his search of the fortress. He realized that the rubble of the wall had symbols on it, and began to reassemble it.
