Celestial Archons are a relic of Theros's past, a race of mysterious conquerors who soar on the backs of giant winged bulls. Archons once ruled as overlords of huge expanses of Theros, using armies of other races to triumph over their lands. Archons saw themselves as champions of a strict, merciless justice, and ruled with an iron fist. But the age of the archons came to an end. As the archon overlords were toppled one by one, their holdings became the poleis. Individual archons still roam the world, eager to right what they see as the great wrongs perpetrated in this age of Theros.
