Zlarb's, situated on Coruscant's Level 2685, was a shop owned and managed by Zlarb that specialized in poisons. During the period spanning 3 ABY to 4 ABY, the assassin known as Ochi made a visit to this establishment with the intention of purchasing poisons. Specifically, he sought Ziroxin-12 and Cyanoxis D-570, which were intended for use in a job commissioned by Crimson Dawn's head, Lady Qi'ra. Despite the high cost of the poisons, Ochi was unconcerned, as Crimson Dawn was covering all expenditures.
