The Namzaqu

Feng was told by his master in God's Gate that the huge stone door set into the floor of the valley will someday need to be opened. To do this requires a magical key called the Namzaqu. On the day the first gargantuan arrived, Feng's master died, but before he did he told Feng that he believed now was the time for the Namzaqu to be found. As the new guardian of God's Gate, it was Feng's duty to seek out the key...
Researching in the archives of the Universal Church in Volscia Mera, Feng discovered an old book in which some scholar tried to recreate the lost language of the Fallen Kingdom of Urcia. Flipping through the dictionary, he was surprised to find the word "namzaqu." Rather than being a proper name, it's a simple word. It means "key." Armed with this knowledge Feng checked the grammar chapters. The word namzaqu could be either singular or plural... so there might be just one key, or there could be many.
