A character's race can have an influence on virtually every one of their abilities. A fifth race, ratling, was introduced in Legend of Grimrock II.
The most populous of the sentient races in the world, humans see themselves as the keepers of order and peace but not all the other beings agree with their definition of laws or where the borders of nations are drawn.
Unlike humans, Minotaurs don't associate power with wealth or aristocracy but with strength and feats of bravery. They are often found in places where they are most likely to cause problems like in overcrowded port cities and in the legions of warring nations. Minotaurs are tolerated in the cities only because of their ability to do hard labor without rest as long as beer and meat is provided.
Lizardmen prefer to live in the vast deserts, woods and swamps of the realm but during times of severe drought or when the realm has been ravaged by wars, some of them have been forced to flee to human cities where they often end up as beggars and petty criminals. Humans usually don't trust them and lizardmen are often viewed as being capricious and deceitful.
Because insectoids mostly keep to themselves and they rarely wander into the lands populated by other races, very little is actually known of their culture or history. People often rumor of hidden underground insectoid cities and great libraries filled with arcane knowledge.
There is no place in the Northern Realms without ratlings. They have spread all over the lands as they seem to wander all the time and stay seldom in one place for a long time. Ratlings aren’t that well liked because of their scruff looks and fear of contagious diseases, but hardly anyone denies the fact that they know their way around the realms and that they are some of the most hardy creatures in the world.
