Rollay was a scientist working at the jungle facility in ancient Neopia. After a while he went mad, due to the influence of the corrupted Circle of Twelve, and started creating lizard monsters to overrun the facility; eventually, he even turned himself into one.
A thousand years after that, though, the NeoQuest hero came and fought him to find answers to his quest. Being a kill-or-be-killed situation, the hero slew Rollay and managed to get a few, sane words out of his dying breath. At his defeat, he slithered into the underground lake behind him and never resurfaced.
