People of the world

Global
All races found in the 5e PHB can be found in Miorine with the distinct exception of the Half-Orc. While the pairing between Orc and Human is possible, the offspring are despised by both races, but for wildly different reasons. This often results in the newborn being discarded.

Tieflings are the rarest race to encounter but they can be found in or near most major cities. Many take an affinity to living in the Imiant Mountans with the largest settlements being Orod Held and Endlosa.

Those who live in Imorealia
Elves and Humans are the most common races that live in Imorealia. Half-Elves can be found in many cities and towns. With their hardier constitutions they are more likely to travel further than their full blooded Elven cousins. Gnomes call the northern Imiant Mountains their ancestral home. Dragonborn are very common in the city of Zadhir although their true origin has been lost to history.

The Elves of Imorealia are a highly religious people. Believing strongly in the Teaching's of Sterris, they structure their society around their beliefs and they do not hide it. They are generally welcoming of others, but the assimilation of new cultures is a slow process, if it happens at all.

Humans have been a major proponent in the development of Imorealia for many hundreds of years. Not always a positive influence, but an influence nonetheless; Humans are welcomed within Elven society and Elves that choose to start and raise families with Humans are not looked down upon. Half-Elves and other mixed breed children are not mistreated, but due to their considerably shorter lifespans they are often passed over for many traditional roles and experiences available to full blooded Elves.

Orcs were a problem in ages past, but now they generally keep to themselves. Many wars have been waged by Orcs against Elves and Humans and anyone else that the Orcs felt they could defeat. They are now a nomadic people that live in the Blood Fields and rarely is anything beyond the odd raiding party even rumored about. While they most certainly are not philosophers, they are by no means stupid either. They are quick to anger and firmly believe in violence being an answer, but they can be reasoned with.

Rowenton, Home of the Dwarves
Dwarves. As far as the eye can see. Which isn't very far if you don't have darkvision because they usually stay under the mountains (that still need a name) within their capital city of Thramz. There is a large Gnome population within the underground city as well.

Humans and some Elves make up the majority of the above ground population overall.
