Urakta

The Urakta (more commonly known as Rats) are a varied race of synapsid-like creatures endemic to the Outwash plane. They borrow traits from both reptiles and mammals. They have long, pointed, snouted faces, a bipedal and hunched posture, and are covered in a layer of leathery, earth-tone skin. They are intelligent, having their own society within the sewers of the Outwash, being able to verbally communicate, and having a rather complex social hierarchy.

Biology
The Urakta are a bipedal sub-species of the White-eyes, a fellow species of the Outwash, sharing many similarities with their progenitors, such as obviously striking white eyes and dull earth-toned skin. Their eyes, which can protrude in any number of patterns from random sockets placed throughout the skull, oftentimes break natural symmetry, with each individual having some variance. Commonly, Rats will have four/five eyes, with more or less becoming increasingly rare, although two is incredibly rare and one is almost unheard of.

Urakta have two growth stages, a young stage where the Rat will grow to an average of two feet high, with slight variation, it will stay in this form until it has reached a certain social standing, its metamorphosis brought on from pheromones released from nearby Urakta. The second stage is much larger, standing an average of five feet tall, but changes outside of proportions are very minimal except for the arms, which will increase drastically in length. In their adult form the Rat is near permanently bipedal, as it will no longer need its front legs (now arms) to aid in running. Rats mature very quickly, often becoming adults within the first 4 years of their life, however even with their quick growth cycle, their reckless lifestyles still see high pre-adult mortality.

It is rare that Rats will grow any larger, however not unheard of in particular individuals, such as the Lord of Rats, a freakishly large individual who's growth never capped, and continued to grow year after year. The Lord is the current ruler of the Rats within Outwash, attaining this title after killing and eating the previous council, known collectively as the Rat King.

Unusually for a species, the creatures also seem capable of very innacurate plane hopping, with instances of smaller communal groups popping up in seemingly unusual planes, however instances of this happening are rare.
