Little is known of the origins of Kaarthik, save for it being settled by the territorial Kroot which are native to The Sands of Serrakhan. Constructed from the bones and hides of their successful hunts within the dune sea, the city of Kaarthik stands as one of the only Kroot settlements within Osira. Many rumors spread across the Serrakhan Sultanate of unfortunate travellers and merchants captured by the Kroot and taken back to the city as sacrificial offerings to their savage gods.
