Sith Wyrm
originally created by Naga Sadow, this immense reptilian insect lived in a subterranean lair on the moon of Yavin 4. The ancient Massassi worshipped it as a god, until Exar Kun killed the beast in an effort to prove his worth to Freedon Nadd. The Sith Wyrm was originally an infant space slug which was captured and altered using Sith alchemy. The slug had attached itself to Naga Sadow's personal starship, and Sadow chose to keep the beast alive and use it in experiments in magical alteration of physical forms. Jedi historians believed that there was only one Sith Wyrm, as there was no record of another space slug being captured and altered in any way.
