Maa'lon was a god of the Hut'eri on Dellah.
According to Clarence, the People of the Worldsphere banished their gods and imprisoned them inside Dellah. They escaped during the end of the 26th century and one of them assumed the identity of Maa'lon. (PROSE: Where Angels Fear) After Bernice Summerfield and those not converted to worshipping the gods were evacuated from the planet, Maa'lon was killed by Tehke. (PROSE: Twilight of the Gods)
