Planet Zeria

Before it was foaming with lava, inhabitants lived privileged lives. The planet's diverse resources provided land to grow crops and rock to mine. Earthquakes were always common, but a series of earthquakes that lasted days made the planet's foundation crack beneath residents' feet, spewing out lava that killed dozens, left others injured. Lava killed crops, filled mineshafts, and forced those that kept their lives to evacuate.

Story
A myth surrounds the disaster of Planet Zeria, involving a miner by the name of Terrance and his clumsiness. One night he'd argued with his wife, left home to work an extra shift at the mineshaft. Guy hit the rocks till sunrise; he hadn't realized the sun had peaked while inside the mineshaft. Hit the rocks so hard, so deep, he opened a mile-long pocket of boiling lava. Rocks caved in on him and the lava took care of the rest, caused the earthquakes. Former residents, who've taken shelter on Oprone, the safest known planet in the galaxy, continue to treat the legend like fact.
