The subgroup of raa-dyan di-roa beliefs known as a mia-o'daalad naal-di-'sala are categorised as local di-roa traditions that place a small amount of emphasis (if any) on worshipping the o'kaara-isala.
This mia-o'daalad is thought to have at one point been highly common in Central Syana, evidenced by the absence of oral tradition or local mythology regarding the o'kaara-isala. However, the only traditions that can be classified as naal-di-'sala in the modern day are a small handful of localised faiths found on the south coast of Bia-o'loma-di-kakaamisal Island.
This sub-category of di-roa faith is the largest of the o'mia-raa-dyan-o'daalad and includes all of the few remaining raa-dyan di-roa traditions that can be found in the region of Syana Di-'maar. Within this region, belief in raa-dyan di-roa is most common in the villages surrounding the city of Di-o'ni-kaara, where almost all followers of a mia-o'daalad naal-di-'sala can be found. Although, even within these less urbanised villages, it is predominantly the older generation who follow di-roa tradition, as opposed to much of the younger population who are much more likley to be followers of raa-dyan di-akara-so.
Whilst a mia-o'daalad naal-di-'sala is primarily categorised as having the minor deities not be worshipped in the same way as gods and major deities, there are also other key characteristics that set this mia-o'daalad apart from the neighboruing Mokosan beliefs and traditions. The most distinguishing of these is how histories and folklore are preserved through the passing down of heirloom objects such as carved stones and wooden medallions, which are often etched with pictures retelling the events of some historical or mythological tale.
It is also common for larger standing stones to be erected in the centre of villages that tell an often highly mythological story about the founding of that village and the origins of the people who live in that area. Some older villages and settlements in this region, who at one point in history would have followed the traditions of a mia-o'daalad naal-di-'sala, have standing stones that date back hundreds of years.
This pattern of using physical objects to tell local history as opposed to oral tradition is broken, however, by the small sub-group of this mia-raa-dyan-o'daalad found further along the coast to the east of Di-o'ni-kaara. This smaller, highly local branch is known as a mia-o'daalad naal-di-'sala di-'sad, and was historically subject to a lot of influence from Mokosan beliefs. This means that the primary difference between eastern and regular naal-di-'sala faiths is not only location but also how histories and folklore is passed down through the generations.
Unlike the rest of a mia-o'daalad naal-di-'sala, the eastern variety of these traditions has assimilated the Mokosan practice of oral recitations of events as well as the chanting of long lineages of local rulers. This adoption of practices unlike the other traditions in this mia-o'daalad is almolst certainly a result of the naal-di-'sala di-'sad faiths being found on the border of what were once the Balisan and Mokosan nations.
Even though the greater Di-o'ni-kaara metropolitan area has a population of around 1,750,000 people, a 2021 poll estimated there to be as little as 12 thousand followers of naal-di-'sala tradition. With the smaller eastern subgroup of a mia-o'daalad naal-di-'sala di-'sad having no more than 2 thousand to 3 thousand followers according to estimates made by local religious historians.
