The Last Story/Stargazers' Tower

After Mirania gives Warren the medicine, head downstairs and speak to Lisa. Before she returns home, she'd like you to bring her to Stargazers' Tower, a place she describes as being very special to her. Here, Lisa will show you her "lucky star". In Seek Mode, look left to the goddess statue, then right to the blue star, and up to the twin stars. After the cutscene, speak to Lisa. You can either "talk to her", or "touch her" (trying to touch her more than once results in a comedic cutscene in which Zael falls off Stargazers' Tower). Talk to her to progress the storyline. After, Lisa leaves for home, and you return to the tavern, alone. Head to your room and speak to Dagran, who advises you to get some rest, as your next task begins tomorrow.
