Allies of the Ghasts of Leng. Semas are small creatures from the Plateau of Leng, and they are commonly found in the company of ghasts of Leng (see page 164) and kaveph (see page 225), acting as pets toward the larger creatures. Semas are loyal to the ghasts, going so far as to defend their threatened masters. Likewise, the ghasts are always sure to throw the semas a few scraps of meat during the ghasts' notorious feeding frenzies.
