One of the many guilds of Greyhawk, the Assassins Guild has far reaching influence across the Flanaess. The citizenry views this guild with both a sense of awe and dread. It is said that they openly kill almost anyone of their choosing thanks to some peculiar legal loopholes. This claim is not necessarily unfounded, as two members of the city's directing oligarchy are assassins.
It is no secret that the Assassins Guild has a long standing feud with the Thieves Guild. Less well known, however, is that the guild had been hired by an foreign government to assassinate some members of the party. The assassination attempt was not carried out successfully, leaving a blemish on the almost spotless record - probably the reason for its occurrence being officially denied.
For security reasons, most guild training occurs outside the City of Greyhawk. Notably, the peculiar manor along the River Road is one such training camp.
