I mean no disrespect... but do understand I take great pride in being a mage of Friege. With the murder of my parents and my brother... it pains me to sit here doing nothing.
Ishtar (Japanese: イシュタルIshtar) was a scion of House Friege of Grannvale, daughter of its Duke Bloom, a full-blooded descendant of the CrusaderThrud and the inheritor of the Mjölnir. Widely renowned as a thunder mage of immense power and dubbed the "goddess of lightning" (Japanese: 雷神thunder god), she was betrothed to Grannvale's crown prince Julius and served as a warrior in his service, aiding her family in their occupation of the Munster District and later fighting to defend the capital Belhalla from Seliph's impending army.
During Leif's escape from the prison in Munster, Ishtar was present in a room in the centre of the complex, with Julius while he and Manfroy were conferring with Veld, the Loptr Church bishop in charge of Thracia's north, on the proceedings of the child hunts of the region. Ishtar was questioned by the three about her family's reluctance to forcibly storm the city of Tahra to begin the hunt there, and when she raised her family's concerns about the immorality of the hunts, Julius attempted to assauge her concerns before taking her away from the conference to observe the flower garden of the complex's yard.
Around the time that Leif's army is marching on Leonster's eastern gate, Julius came down with a severe fever and was hospitalized in Ishtar's quarters in Conote. Refusing to have him attended by Loptr Church bishops, Ishtar travelled to Leonster to find Saias, seeking his assistance in healing Julius. After the fall of Fort Danzich and Leif's army's subsequent escape from being cornered there, Ishtar arrived with Julius, who expressed his disappointment with the performance of Friege's forces. She was then escorted by Julius to Miletos at the behest of Hilda, instead of being allowed to assist her father at Conote, but not before she was warned to not see Reinhardt again on pain of his death.
There are two different variations of Ishtar available to Heroes. The normal variation of Ishtar, based on her Genealogy of the Holy War incarnation, is one of the characters added to the game in the Hellfire update, and became available for summoning by players on May 10, 2018. A performance-themed variation of Ishtar, credited to Thracia 776 despite her status as a minor NPC in that game, was made available between the period of September 6, 2019 through October 7, 2019 as part of the summoning event surrounding the launch of the A Splendid Soiree update.
