Falstaff's Gang is a band of thieves and mercenaries led by Falstaff.
In its original incarnation the gang consisted of John Oldcastle, his protege Harry Monmouth and the marksman Pistol. Together the three of them pulled jobs all over Sydney. Eventually, Harry left to pursue a career as an independent mercenary. Taking the name Falstaff, Oldcastle recruited more criminals into his gang. They were eventually recruited by the Illuminati to safeguard the secret society's treasury on Eastcheap Isle.
Real World Background
All the members of Falstaff's gang are named after characters in Shakespeare's Henry IV plays featuring the original Falstaff; see the original entries for further information.
