Nations:
Erebia:
The central continent, with Emeria to the west, Lyria to the east and Aethia to the south.
Northern Erebia:
Elerian Nations: Kingdom of York, Republic of Saari, Empire of Ruthenia, Kingdom of Skane, Rheinberg Confederation
A generally temperate region around York and Rheinberg, growing colder around Skane, Saari and Ruthenia's northern areas. Ruthenia itself straddles both northern Erebia and northern Lyria, facing Calamities both in its northern reaches and on the borders between it and Tianchao to the south. Northern Erebia has the highest concentration of Elerian Academies with three; Solrise Academy in York, Moonset Academy in Ruthenia and Starfall Academy in Rheinberg. Northern Erebia is of great importance to the Elerian Order as the region where the Order was founded; the northern inner regions of Ruthenia and the far north of Skane and Saari are constantly plagued by Calamities and Fiends, and the Order was founded to help protect the victims of Calamities before expanding their scope to the rest of Parvain. The Elerian Order itself is headed from Rheinberg, which also governs all of its regional operations in Erebia.

Southern Erebia:
Elerian Nations: Kingdom of Miletos, Serene Kingdom of Marinia
A hot region bordering the Mittel Sea, which is bordered by the continent of Aethia to the south and Lyria to the east. The southern reaches of Rheinberg reaches into this region. Unlike Northern Erebia, Southern Erebia has had the benefit of being insulated from Calamities due to a combination of geographical barriers and rich Alphinite stores. As such, the Elerian Order has yet to spread into this region heavily beyond a few outposts and centers, with most Miletan and Marinian prospects for the Order having to go to the northern Erebian academies instead. 

Lyria:
Elerian Nations: Kingdom of Yamajima, Kingdom of Tianchao, Suvarna Republic
The eastern continent, with Ruthenia standing half in Lyria and half in Erebia to the west. A temperate region to the north, growing tropical towards the south. Lyria's Calamities have been traditionally fought by national governments, having never developed an equivalent to the Elerian Order until the Order spread from Erebia. Lyria is generally Alphinite-poor, unlike other regions, rendering it heavily Calamity-prone. As such, Lyrian nations have often imported heavy amounts of Alphinite from Erebia and Emeria to shore up their own defenses against Calamities and Fiends, as well as developing technology with which to repel the hordes of Fiends and to catch up to the rest of the world outside of Lyria. The sole Elerian Academy in Lyria is located in Yamajima, Blue Moon Academy.

Emeria:
The western continent, divided into two halves.
Northern Emeria:
Elerian Nations: Vespalian Federation, Republic of Dine
A smaller region than the others, most of the north of Emeria is ravaged by snow and permanent Calamities, forcing most of the inhabitants to dwell in the small space between the arctic regions and the border of Chaldea to the south. Many smaller polities and nations occupy northern Emeria; Dine and Vespalia, being the biggest and most economically secure occupy the role of regional superpowers and are the base for Elerian Order missions in the region. North Emeria is also home to some of the bigger stores of Alphinite in Parvain, allowing them to fortify the northern reaches with Alphinite-enriched defenses. Northern Emeria is home to Nightfall Academy, located in Vespalia. 

Southern Emeria:
Elerian Nations: Holy Republic of Chaldea, Kingdom of Culhua
One of the few regions of the world safe from Calamities due to a combination of natural Alphinite stores, geographical barriers and distance from Calamity epicenters, Southern Emeria has adopted the opposite approach from southern Erebia, with many of their national armies nonetheless drilling and training in case Calamities spread from the southern polar regions or through north Emeria. As such, south Emeria is home to two Elerian Academies despite only having two nations sponsored by the Elerian Order, Eventide Academy in Chaldea and Daybreak Academy in Culhua.

Aethia:
Elerian Nations: Kingdom of Phoenicis, Republic of Nyeni, Kingdom of Kemet
A notoriously Calamity-ridden land, the massive Dayar Desert that occupies most of the inner continent and southern half is ridden with Calamities and Fiends hidden in the sands and the constant storms and disasters. As such, most of the Aethian nations occupy the coasts, separated from each other and needing to make crossings via air or sea to make contact with other nations. Due to the difficulty of transporting supplies to and from Aethia, only the nations directly bordering the Mittel Sea and closest to southern Erebia, Phoenicis, Nyeni and Kemet, have joined the nations making use of the services of the Elerian Order. The northern coast of Aethia, however, is abundant in Alphinite, both local and imported from the equally Alphinite-rich southern Erebian nations, allowwing the nations to protect themselves adequately. The Elerian Academy of the region is Undertide Academy, located in Phoenicis.
