Blue dragon (Dragonkin)
Kirygosa or just Kiry is the sister of Arygos. Her clutch was rescued by Korialstrasz after Malygos had gone mad and delivered to Nozdormu and later to the red dragonflight. She was kidnapped by the Twilight Father, but eventually escaped on her own.
Twilight of the Aspects
During the Nexus War, she opposed her brother Arygos and Malygos and sided with those who opposed Blue Aspect's war. Shortly before the war ended, her mate Jarygos was killed and Kirygosa went missing, believing she fell in a battle.
In fact, Kirygosa was kidnapped by the Twilight's Hammer shortly before she was to lay her first clutch of eggs. The cult experimented on her unhatched children, continuing Nefarian's research into the chromatic dragonflight. The Twilight Father forced her to witness the attack on Wyrmrest Temple and was held captive there. She was planned to be forced to mate with Chromatus, the five-headed dragon deciding that the child of an Aspect would be strong enough to bear living chromatic offspring. Before this happened, however, she was able to escape and returned back to her flight and told everything she learned about the cult as well as of the betrayal of Arygos to Kalecgos, Alexstrasza and Thrall. When the temple was liberated, Kirygosa searched cultist's bodies but the body of the Twilight Father was not among them.
Tides of War
Kirygosa was one of the few remaining dragons at the Nexus after the defeat of Deathwing. When a group of dragons escorting the Focusing Iris to a safe location were murdered, Kiry, alongside Alagosa and Banagos, investigated the sight before Kalecgos flew off to chase the artifact down. She was left to be the voice of Kalec in the Nexus while he was gone.
After the destruction of Theramore Isle, the Focusing Iris vanished again and Kalec returned home, defeated. Kalec told her what had happened and Kiry believed that there was a distinct possibility the Iris was taken this time by Jaina Proudmoore.
When Kalecgos returned yet again, Kirygosa told Kalecgos that there were only a handful of the blue dragons who still stayed behind at the Nexus. When Kalec asked her what she would do without anything holding her back, Kiry responded that she would go see places where the oceans didn't have ice, and where the winds weren't cold. Kalecgos disbanded the blue dragonflight then, and Kirygosa told him that if she was ever needed, to look for her in tropical climates.
