If it is not too late, here is my entry.
Wanted to have this by Saturday, but with the board down, I wasn't sure if the challenge would be extended.
Tír nAill or Hvítramannaland (also known as Annwn, Albania, Tír-na-nÓg, Avalon, or Hy-Brasil)
A partial abstract of a vexology file from the joint UN Bureau of Chronology and International Uchronic Science Foundation’s investigation of Social Impacts of Symbolism across Temporal and Paratemporal Human Cultures
Here we have the flag for the nation of Tír nAill located in the northeast sector of Continent V (OTL North America) found in paratemporality 12b:-13h:103hn (of the Scandi-Eire subsector), henceforth designated SE12b for brevity. This paratemporality has many cultural and mythical cross references with legends and mythologies of OTL…
…During the Vinland colonization of this Paratemporality’s Viking era UNBC chrononauts were able to determine that the myth of the “
Great Ireland” or Hvítramannaland had a basis in fact for SE12b. Only in this case it was not early Irish settlers to Continent V, but a group of Continent V aborigines, denoted hence forth as Skræling*, that had a genetic mutation in the oculocutaneous albinism II (OCA2) gene, causing a form of albinism manifesting as low or no skin pigment and hair color of white, blond, strawberry blonde, and occasionally a stunted ginger. Chrononaut investigations have determined that the Norse colonizers assumed the Skræling of being Irish due to their skin and hair color, as well as their dress of full body coverings to protect their skin. Stories brought back by the Norse to Continent I (OTL Europe) mentioned the nation of Great Ireland. This would have the effect later on of several expeditions of Irish priests and settlers seeking out Hvítramannaland. While not numerous, the White Skræling would be found by Irish priests and converted to catholicism as lost lambs of the
Papar who had left Subcontinent X (OTL Greenland). Those fisherman and settlers that reached Continent V would eventually intermarry with the White Skræling…
…as the culture of Tír nAill the main aspect of their religious life was slow identification of the Shawnee Great Spirit, Mishe Moneto, with the Christian God. The eventual identification of the Thunderbirds, called Nenimkee or Binesi in old ni’Shawnee, in their aspect as winged men with the angels of the Christian bible, helped to start the schism from the Catholic Church in Rome…
…The flag of Tír nAill has the traditional Cross and Wheel symbol of the Tír nAill Catholic Church. The wheel represents the breaking wheel that many Tír nAill people were executed upon by the Roman Catholic forces fighting this rebelling nation. The cross is that associated with St Patrika, not associated with St Patrick OTL. The blue top border represents the sky and heaven, while the green represents the earth and life…
*Genetic research by the UNBC would show the White Skræling to be of Shawnee people of Algonquian origin.
