Jango Fett is hired by Dreddon the Hutt to sneaks into Antonin’s palace and kill the rival Vigo. Jango finds Antonin drinking his last bottle of Alderaanian Wine. The two have a brief chat and Jango kills him. Unknown to Jango, Antonin has hired Zam Wesell to kill Dreddon, which she does while Jango kills Antonin.
