Burvixese
The Burvixese race evolved on the planet Arcturus 1, progressing from turtle-like swamp dwellers to a benevolent, highly technological society in just over fifteen million Earth years. Although the Burvixese had the wherewithal to build crude interplanetary vessels, they preferred to remain on the comfortable damp surface of their world and explore the galaxy through HyperWave communication. Using this method, the Burvixese made contact with several neighboring alien cultures, including the Utwig, the Gg, and unfortunately, the Druuge, whom the Burvixese would have been much better off never finding. For many decades, the Burvixese exchanged information with these races, trading technological, historical and philosophical facts and theories, until the fateful year 2142. It was then that the Gg announced that they had come under attack by a unknown alien race, who appeared to want nothing less than their complete annihilation. The Gg surmised that the hostile race, the Kohr-Ah, had located them using the Gg's HyperWave transmissions. Knowing that they had little chance of survival, the Gg warned the Burvixese that, unless they restricted their own transmissions, they too might face a gruesome fate.
Being a charitable race, before the Burvixese turned off their HyperWave transmitters, they shared the Gg's warning with the Druuge. But it was too late. The Druuge's powerful advertising beacons had already attracted the attention of the murderous Kohr-Ah, who, having finished with the Gg, began moving in the general direction of the Persei constellation, home of the Druuge. Realizing their peril, the Druuge took immediate action. They ceased all transmissions and sent a task force of their fastest ships to the moon of the Burvixese world. Once there, the task force assembled a huge HyperWave broadcaster on the moon's surface. When it was complete, the Druuge activated the unit which began emitting powerful HyperWave signals, focused directly toward the oncoming Kohr-Ah fleet. The Druuge hoped that the hostile aliens would change course toward the Burvixese planet and fail to find their own worlds. Unfortunately, this ruse was all too effective: the Kohr-Ah changed course, attacked the poor Burvixese and, sadly, destroyed them all in three days of orbital bombardment.
