Notebook

 * Estelle and Joshua located the cult's lodge. We were able to make it there safely thanks to Chief Sergei and Sergeant Major Seeker.
 * We rendezvoused with Estelle and Joshua in front of the Sun Fort. We began our infiltration immediately.
 * Inside what looked like the fort commander's room, we saw the same symbol we found at the Moon Temple. This must be where the cult's emblem originated from.
 * Located a research facility. Two mafiosos under the influence of the drug became demons and attacked us.
 * There is likely information about the cult's inner workings nearby. We should look around.
 * Terminal 01 lock released.
 * Terminal 02 lock released.
 * Terminal 03 lock released.
 * We found the missing persons imprisoned. We should get them out immediately.
 * We confirmed the safety of the missing persons and then explained the situation. They will sit tight until help arrives.
 * Marconi and his henchmen are also imprisoned. Judging it too dangerous to leave them in their cells, we released them as well.
 * Upon leaving the jail block, we were stopped by Ernest. He also demonized and attacked us, but we were able to subdue him.
 * We battled and suppressed Garcia Rossi, who was under the drug's control. He was also on the verge of demonizing, but he valiantly fought back the drug's effects and regained his sanity.
 * Joachim is just up ahead. Let's make our final preparations and then close this case!
