Nyna Calixte's apartment was located on the planet Coruscant. In 138 ABY, sometime after the rescue of Princess Marasiah Fel from Korriban, Imperial Regent Morlish Veed spent the night there with Moff Nyna Calixte.
Not long after Veed discovered that Moff Calixte was in fact Emperor Roan Fel's spy, he entered her apartment pretending that he thought Konrad Rus, head of the Imperial Mission, was the spy and offered Calixte a drink to celebrate. However, she quickly discovered the drink was poisoned and the two began shooting at each other. The conflict ended when Calixte fell from her balcony seemingly to her death.
