OOC: OK here is what the Thermolians were back in the days of the Borg Forum and The SE3 Ladder. They were actually temporal before SE4 made it fashionable! Of late they have become more religious where it is allowed and more Organic when religion is suppressed. But they are still the same old dead meat
Ladder Data on the Thermolians:
The Thermolians are an energy based race which evolved in the Quasars at the center of the galaxy. They revivify the dead bodies of their victims in order to interact in normal space. Their average lifespan is eternal. They have very little technology of their own, and are quite adept at stealing what they need from other races. They do tend to adapt these designs to their own manufacturing methods and materials.
The Thermolians are aggressive and known as devious schemers.
The Thermolians are a dictatorial empire dedicated to spreading its influence across the galaxy. The government keeps all of its citizens in line and allows no dissention. The society is ruled absolutely by the current emperor, with new emperors coming to power only after the current one has been killed in mortal combat by another Thermolian. This has only been known to happen two times in the Last three billion years. There are the occasional rebellions, but they are put down quickly and violently. Most of the galaxy has heard of the fate that The Last First Speaker suffered when he aspired to the throne.
Originally the Thermolians were not considered much of a threat to other species. They were largely unknown, being mentioned only in old myths. This is largely due to the fact that the Thermolians only leave their Quasars once every half million years or so, although a few remain on occupied worlds and never return. These are usually thought to be demons and devils by the local populations.
