Tulun Suli: The Genie-Kin known as Suli were one of the races that were pulled into Tulun via the Rift created during the time of The Reckoning. Very much attuned to the Elemental Planes though not associated with any one particular type, they became natural mediators between the various Elemental Courts of Kajir. Their highly charismatic personalities make them perfect diplomats as well, and they are often employed by The Elemental Court to approach others on their behalf.
Place of Origin: Though they come from another realm of existence, all of the Suli found in Tulun come from the land of Kajir.
