The fortress, nicknamed the forbidden fortress, was built and held by the savage Ka'vaDak people. The Ka'vaDak built this temple after they were constantly being attacked and raided. Their scrolls told of the hardships they faced as their 1,540 men built this fortress in intense heat and blizzards, and their staggling loses of up to 250 men a week. The temple was built to withstand any assault. The people weren't so lucky as proven during the Thirteen Years War .
