Näjenayon

Näjenayon (Xiri: faná’ayo mu’óyo) is the ritual recital of Xiyeru lore. It was traditionally an oral tradition of storytelling, but since the invention of writing (c. 500 BGS) it has also included the transcription of lore and reproduction of historical almanacs.

In the 10th century AGS, Lavondu communities in T'ugü undertook a vast project known as Käzñon ("rearrangement" or "restructuring"), involving the preservation, reformation and reorganisation of ancestral Xiyeru culture and modern society. One important step of this process was the formal definition of a generalised astronomical calendar, the Öcizñox, and the subsequent chronologisation of historical records. The previous ~1400 years of written Xiyeru history had not recorded actual dates, but detailed calendrical information nonetheless. This allowed contemporary Xiyeru scholars to calculate specific dates for major events and calibrate the chronology. The entirety of the known history of the world was arranged into discrete eras, each named for an important establishing event. The complete, assembled history covers several millennia and includes many eras which are internally structured, but unable to be definitely positioned with respect to the others.

Sunrise period (476 BGS – 67 AGS)
The earliest period discussed in actual written historical record is the Sunrise period (Möxale: Ovzija nä’än), which starts with the invention of writing (among many other things) and ends with the discovery of T'ugü and first contact with the Öb. This era's history consists mostly of biographies of the fifteen Aéruwe’a who served during this time. After contact, it was augmented with knowledge of T'ugü, with later records of the period including some retrospective commentary of the life of the Öb pre-contact. In particular, the cultural significance of cimcim and the separation of Öb into the agricultural lowlanders and semi-nomadic highlanders are described.
