Lin'a'an has come to the Crèche with Inquisitor W’wargaz, who was sent to locate and retrieve mystical ultimate weapon against ghaik. Still, while it has not been found, Lin'a'an accompanies guards at the Rosymorn Monastery Basement entrance.
As the party enters the Crèche, they might hear Warrior Khunaruth arguing with Lin’a’an about the Inquisition’s presence and activities within the Crèche and its surroundings, the latter scolding the warrior for negligence they notice almost everywhere and for lack of efforts to find the weapon.
Lin'a'an will become hostile to the party if they fail to explain their attempt to infiltrate the Crèche, or if they progress far enough in The Githyanki Warrior quest.
