The Northern Territory of Sohma now has new enemies, most of them dropping rare Materials needed for some of your high level Crafting. Lesser Dragons drop meteorites, Skeleton Soldiers drop nereidstones, Amber Princesses drop Moon Pearls, and Jatayus drop Angelstones and Nereidstones as well. Make sure to spend time farming them if you want to craft some great equipment. When ready, head north to the Signesilica
Use the healing point and savepoint. The path to the west is blocked by spikes so you have no choice but to head north. Before doing so, loot the Anti-Death Amulet from the chest in the corner of the first room.
Head north then right. Enter the first door north then to the immediate left. This will take you to a small room containing a CQC Program Eta. Make your way to the hallway to the right then head north. There’s another small room to the northeast that has Mental Stimulant x2.
Continue to the next large square room with a single Ravenne enemy. This enemy drops Salamanderstones for Crafting as well. After defeating it, loot the Signet Card: Angel Feather from the chest in the southeast corner.
Head to the next room then loot the Attack Seeds and Intelligence Seeds from the small room to the north. There’s an Ash Dragon waiting in the following room so head there and avoid getting caught in the middle of the doorway. After defeating it, continue south.
If you have accepted the sidequest “Open Season on Ruphin”, you can find it alone in the room to the east. Defeat it and loot the Mithril Rod from the chest in the corner. Leave the room and head west this time. You’ll find yet another Ravenne enemy right before the savepoint. Defeat it once more then loot the Moonlight Signets, Vol. 2 from the small room to the north. You can’t head to the south yet so continue to the west and save your game.
Head downstairs and face the Crystal Guardian. This boss is only capable of unleashing physical attacks so as long as you keep your non-melee characters spread out and at a distance, it’s possible to keep it busy and focused on your melee fighters as long as you attack it aggressively. This should be an easy battle since it doesn’t have any dangerous moves that may incapacitate or disable many of your characters.
After defeating the Crystal Guardian, continue to the statue and wait until Anne successfully opens it. Head inside to be transported to an unknown expanse. Loot the Orb of Antiquity from the chest then follow Relia up the ramp to continue with a cutscene.
After the cutscene, don’t leave yet; loot the two chests around the ruins to get a Founder’s Signets, Vol. 2 and Parchment. After looting them, exit the expanse then backtrack to the savepoint. From there, the doorway to the south should be open.
Clear the corridors then loot the Pneuma Signets, Vol 2 from there. Follow the path until you reach the location’s entrance. Use the healing point if you want then leave the place. Once you’re outside, you should be able to use the Communicator again to transport your party to the ship. You’ll also unlock the option to transport in front of the Signesilica moving forward.
The last set of sidequests will become available here and will come from Santeroule. These will most likely compose of subjugation Quests to some monsters found in Signesilica. After you’ve completely finished all the quests and any pending Private Actions you have in other towns, report back to the Charles D. Goale G to trigger the last private actions in the game there.
