Munish is first encountered in the Moonrise Towers throne room, standing guard over the trial presided by Ketheric Thorm. After the trial ends, Munish moves over to stand guard on the western side of the room, next to the grand door leading into the throne room. Talking with Munish after Isobel has been kidnapped lets him reveal that his family owns a bakery in Baldur's Gate, and that he believes, that their bakery will be spared by the invasion.[1]
If the Nightsong is freed and the Harpers launch their assault on Moonrise Towers, Munish is part of the remaining forces defending Moonrise Towers, and can be encountered in the throne room. Should the party enter the throne room prematurely, or kill a few Absolutists in the hall, he joins combat.
