Pooka are short creatures that generally have a hateful or selfish attitude. They are often ignorant are dense, however there are rare exceptions. They are sometimes used as underlings by unsavory types, or senton suicide missions they are too dim to realize they're being used for.
The pooka used to be known as the sevrock. They were masters of science and magic, but they were careless and eventually through their studies they destroyed themselves and their city. The only remains of their once great culture are the sevrock ruins and the pooka. Mutated shells of what they once was.
