Jai Quallo, a Kaleesh Beast master of male gender, existed throughout the era of the Galactic War. Functioning as a member of the Dust Vipers syndicate, which was active on Tatooine, he was tasked with guarding the entrance to the gang's hideout close to Anchorhead in 3630 BBY. During this time, the Eternal Alliance launched a surprise attack, seeking to recover stolen security protocols from the Alliance base situated on Odessen. Despite engaging the invaders alongside his creatures, Jai Quallo and his beasts were defeated and perished.
