The Gnalor system is a backwater star in the Federation, out of everybody's way, never
really getting noticed. The fourth planet, Gnala, is M-class, and it is here that the
dominant life form of the system evolved. There are two distinct species of sentient
Gnalish, going by the names Gnalish Elt and Gnalish Tarn.
Tarn are a pleasant species of lizard humanoids with part of the Galen DNA Program
residing in their genetic structure. They erect buildings, build starships and interact
with the rest of the Feds. In other words they are a perfectly normal species. The Elt, on
the other hand, are far from normal. Thousands of years ago, another species, unidentified
by the current inhabitants, visited the Gnalor system. They took large numbers of the
native primitive Tarn and genetically modified them into the creatures known as Gnalish
Elt. The early Elt served as soldiers and shock troops for the advanced race, until
something equally mystifying happened and they left.
Bereft of their creators and sustainers, the Elt, with the assistance of the remaining and
now thriving Tarn, managed to survive and prosper. Today they have a bizarre two-caste
society, with the far more powerful but emotionally unstable Elt ostensibly leading a
sturdy and reliable, if superstitious population.
