The race that I would like to add is another team's created protectors, that were placed upon your world, with your team's consent, to see how adaptable the race is to new terrain.
The Kel'nar are a race based upon the dragons of earth mythology. They have the ability to spread knowledge between others of their race through telepathy, allowing them to gain technology and adapt to new strategies at a highly accelerated rate. This has allowed them to reach near-space age technology in five-hundred years, and allows them to learn languages of other races instantaneously by reading the minds of the target race. They have free will and are independent of the (insert name of the alien race creating the protectors), but they will protect those who are persecuted if there is no way for there to be peace. This will cause them to change sides in wars if the side they are fighting with begins to commit atrocities, and will also cause them, if not currently in a war, only to fight wars if they themselves are attacked. Their race has three subspecies that are listed below.
The smallest are the Monitors, they reach the size of hummingbirds, and excel in all forms of mechanical technology, and stealth. They have the appearance of winged, four-legged dragons.
The middle sized are the Rangers, they reach the size of small cars, and excel in aviation and language. They have the appearance of wyverns.
The largest are the Guardians, they reach the size of a large house, and excel in all military aspects, and architecture. They have the appearance of wingless dragons.
The Kel'nar will spend the turn building up in a small mountainous area, and then observing the other races to see which side that they will join, if peace cannot be achieved.
