VYDRA is a world roiled by constant eruptions, but the technologically savvy Vydrans manage to safely divert the lava flows and even harness that thermal energy to power their civilization.  With consummate skill, they build highways and homes out of igneous rock.  There is nothing that science and fire can't accomplish together on Vydra.  This includes their final partings, with funereal rites that always involve a trip to the nearest volcano.  The mourners dress in elaborate heat-resistant costumes, and with the departed they dance.  All the way to the fissure they dance... one last dance before saying goodbye.
