Amstron

History
The Amstrons were once a peaceful race. Their empire partnered with the J'arrodic empire to create a wormhole to another universe.Two astronauts were sent through the wormhole, one an Armstron, the other a J'arrodic. The astronauts both died, but not before they sent the message, "It's the face of the creator", back to the Amstrons and J'arrodic. The Amstrons argued with the J'arrodic over whether the creator was an Amstron or a J'arrodic. The argument became a war.

By 2015, the war was known as the Eternal Dogfight. Alice Obiefune discovered it was captivating beauty that enthralled most observers. Due to her grief over the death of her mother, she was immune to the effect and returned to tell the combatants the truth, which ended the war. (COMIC: The Eternal Dogfight, The Infinite Astronaut)

Circa the 38th century, (COMIC: Doctormania) an Amstron visited the Fluren Temporal Bazaar. (COMIC: Weapons of Past Destruction)
