The Lizard Keepers served as enslaved individuals under the Dathomiri witch known as Zalem. Their specific task involved severing the paws of indigenous lizards, referred to as Kwi, as these paws were crucial for operating the Infinity Gate. Not all maleling slaves were selected to be Lizard Keepers, owing to the high-risk nature of the position. Elevation to the role of Lizard Keeper was exclusively granted by Zalem herself.
During 31 BBY, the Jedi named Quinlan Vos, along with the Givin Yag Shushin, attained the rank of Lizard Keeper. This promotion occurred after Quinlan successfully eliminated a giant Whuffa that was threatening the ongoing excavation area.
