The Zolacians' are tall, lanky marine filterers who once ruled the planet of Zolacia, now known as the planet Hydroth due to a sudden shift in planetary power. Once a xenophobic race, they subjugated their planet's other four sapient races - the Hydrothi, the Zazlotl, the Lyssh and the Ghazra - out of fear. Over millennia they became peaceful, but it was too little, too late - now they have become slaves themselves.
