Raten 5e

Raten are intelligent and spry rat-like humanoids which are quite short, varying from the height of a halfling to that of a dwarf. They've got sharp teeth, a weak but prehensile tail, beady eyes, and a keen nose.

Raten usually live in communities called swarms. These communities are a collection of many families which all live among each other to benefit from one another. When a swarm comes together it is capable of great things and higher intelligence. When enough Raten are brought together they have been known to achieve great things that many others are incapable of, though Raten often aren't ambitious enough to leverage their potential. Because of this, the idea of a large ambitious group of Raten scares many. That resulting fear is what drives many to persecute Raten and drive them into the underground, undercity, or remote locations.
Raten homes are called warrens, and often house many Raten within them. Usually a warren is home to a single bloodline, but circumstances may cause several bloodlines to live within the same warren or even a full swarm in extreme circumstances.

Raten have a stigma against them as dirty, diseased, thieving creatures which bring death and illness. Although they are unorganized, they are quite clean and rarely carry disease. The stigma isn't unwarranted however. Raten stay separate from but close to society, usually in poor conditions such as run down buildings, sewers, or caves. They lack the ambition to form a strong society of their own, and they've been rejected from integrating into others' societies and so leech from existing ones through scavenging and thieving.

Despite their ways and how they are viewed, some Raten manage to find their ambition and strike out on their own. Their reasons can vary widely, much like humans, whether it be to rise above their lot in life, rebel, explore, prove themselves, or countless other aspirations. Most Raten who strike out on their own do so in the attempts to join human societies, and the rare few become adventurers.

Raten names are singular, and short. They never have surnames, though in some occasions they may have titles.
