"If they call Tiamat the Queen, then Jatil is...well...okay not her king...but like her Nephew" - Presidith
Jatil Jivelg (whose name means Cruel Tormentor in Draconic) was a Black Dragon native to Kiston who had massive ambitions. He was encountered by both parties of the It Came From Kiston campaign. The ancestors of the campaign encountered him as a young black dragon, while the descendants met him nearly two thousand years later, as a massive black wyrm.
History
In the early BR era, a young Jatil was already rising to power, having earned the respect and assistance of a tribe of Draco-Orcs who helped him with his early machinations. One notable early mission he had them undertake was to steal a red wyrmling from the Crystal City, hoping to use it as leverage against the Red Dragon families. Unfortunately the kidnapping was sabotaged by The Venship, who would save Presidith the baby red dragon and reunite him with his mother in the city.
In the late 1290s PR, Jatil was now one of the strongest and most terrifying of the dragons still on Kiston, the adult red dragon Presidith admitted that most dragons still on the island worked or served Jatil in some capacity. When Presidith tried to lie to Jatil and hide the presence of The Fated Five on the island, Jatil (off-screen) pinned down Presidith and told him that if he tries to protect the Fated Five again, there will be 6 bodies. Presidith also put the rest of the island on high alert for any sight of Presidith possibly helping five individuals, which made the skies of Kiston an incredibly dangerous place to be for the team.
Jatil preyed on the cowardly Presidith, knowing he always gives in to fear.
