Dryra was the home planet of the Dryrth. It was located in a different galaxy to Earth. By the time the Dryrth achieved centuries of peace, Dryra was a grassy paradise. The Dryrth built villages composed of white buildings with gardens on the roofs.
Ravnok became sickened with life on Dryra and unleashed a virus which killed most of the population. After Ravnok escaped prison with Vartex, they both left the planet. (COMIC: The Lunar Strangers)
