Most of the humans that inhabit Nurna today are descendants from the Aztlani people, who inhabited a continent west of the Ronurna that is under the waters today. After their homeland sunk, eight "fleets" of Aztlani tribes left in order to find a new home, sailing to many points of Nurna's western coast. Many of those "tribe fleets"; such as the wise tribe of the Tula, the magical tribe of the Tharshish or the powerful tribe of the Eanna, settled in what is known today as the Tableland, where they prospered. But all of those tribes were unified by an empire, five hundred years after the sundering of Aztlan. That empire was born of the alliance of two Aztlani tribes of the Tableland: the Tribe of the Sun (the Ra-Nui) and the Tribe of the Moon (the Mu-Nui). Allied by a royal marriage between their chieftains, they became the Naacal, and they control the entire Tableland region since then.
Major language groups and dialects
The Naacal speak a refined version of the Aztlani, the lingua-franca of Nurna. This language derives directly from the one spoken by the descendants of the sunken continent of Aztlan, and legends told that Aztlani people created it while trying to imitate the Kawak language, the tongue of the old dragons, who ruled over rain, earth and forests.
Shared customary codes and values
Tribal Tradition rules: none. Naacal characters keep their racial traits, and they shouldn't respect any other tradition.
The Naacal Empire covers all the Tableland, with the Old Wall at its northern border and the limits of the Snake Rainforest at the south. Its capital is Naacalcan ("City of the Naacal", the Sun and Moon Tribe), where the Tlatoani (the Naacal emperor) has its throne. Tlatoani means "First to Speak", and this refers to the fact that the Naacal Empire is the conjuction of many Aztlani tribes, united by religious and politic alliances. However, the Tlatoani shouldn't be considered a Primus Inter Pares by its name, isn't anything like a "First Among Equals": the Tlatoani is a sacred figure, the embodiment of the Sun God Tama-Nui-Te-Ra, King of the Sky and oldest deity in the Aztlani pantheon. The Tlatoani was the chieftain of the Aztlani Ra-Nui Tribe, and is the head of all political powers in the Naacal Empire. However, the religious and spiritual power is controled by the Cihuacoatl, the "Snake Lady", High Priestess of the whole Naacal pantheon. Just as the Tlatoani descends from Ra-Nui chieftains, the Cihuacoatl descedns from the female chieftains of the Mu-Nui Tribe. Tlatoani and Cihuacoatl presides all over the Naacal Empire from three buildings: the Mu Palace, the Ra Council and the Sun and Moon Pyramid, all of them in Naacalcan. The Mu Palace is their private home, while the Ra Council is where they meet their councellors and the leaders from other Aztlani tribes. The Sun and Moon Pyramid, however, is the religious center of the Naacal Empire, the twin temple of Ra and Mu, king and queen of the Aztlani pantheon. Governors from other Aztlani cities are called Cuautlato ("Speaks as Eagle"), and meet the Tlatoani and the Cihuacoatl every year in the Ra Council. Each one comes from a city of the Tableland, and each of those cities carry the name of the tribe that founded it: Zapocan ("City of the Zapo", the Cloud Tribe), Tulacan ("City of the Tula", the Wise Tribe), Tharshishcan ("City of the Tharshish", the Silverworkers Tribe) and Eannacan ("City of the Eanna", the Prosperous Land Tribe).
