Wizards of Scythia
Marvin the Forgetful
An Old Gnomish Wizard
The party does not know much about Marvin except that he is a wizard who lives in a tower and he has offered to destroy their indentured servant contracts in exchange for two things: 1) Agree to imbibe the experimental potion 2) Perform odd jobs over a period of a year (including reporting on the effects of the potion) in exchange for 100 gold pieces per month.
Faced with the alternative of a lifetime of servitude, all party members agreed to this arrangement.
