You'll notice something is wrong when you're back; Cross the door to the North, then the door to the West and you'll watch a scene and fight some assassins. Kill the clawed ones before they use any 'Death, death, death!' attacks and watch out for the Net attack, which can be annoying. Head West, ignoring the first 2 doors of the hallway, then enter the door heading North and climb the stairs. You'll fight more assassins, then cross the bridge, then fight more assassins twice. You'll find only a couple of non-Etones survivors at the last room. Now go back all the way the main corridor, the head West to the last North door to fight more assassins. Leave the room, head to the last room to the West and enter the new passage. After going down the stairs, ignore the door to the South and the 2 door to the North, entering the last door to the North. Climb the stairs and get a Gold Nugget at the room, the open the door to the South to get an Aquasol DX and a Seal Ar. Now go back and enter the door to the East to fight more assassins. Continue through the next East door (ignore the South path), turn North, then East and check 2 last doors to your North to save a Shevat Agent and Big Joe (Just talk to them). Go back South to the corridor and continue East through a door, then North heading down the Elevator continuing North. Enter the door to the East to watch lots of conversation. Exit the room to watch more scenes, then fight more assassins. Go after Jessie to watch more scenes.

You'll have to form a party (Citan must be in it) to help the Thames. Head to the Thames and talk to the Captain. After explaining the situation, you'll have to go after Stein at the Ethos Dig Site (An island to the North of the Thames). Head inside, take the platform down and cross the door to the West. If you want to fight the Gebler Guard, touch him (Although you won't have an option later), then enter the elevator to the North (You'll watch a scene), exiting to the South. Enter the door to the East (It's the only door you can open here) to reach Zeboim (Each character will have a distinct reaction visiting Zeboim; bringing particularly Elly will result into some interesting lines plot-wise). Cross the bridge, climb the stairs East, then West and open the door. Follow the corridor to the North (Save if you want), open the East door, then head straight East to the last door to your South (You'll fight Gebler Guards on the way). Exit the elevator and proceed North through another corridor, then get the chest to your West. Head East, fight some Gebler Guards and cross another corridor. Head South, circling the room (You'll fight Gebler Guards twice) to the last door to the West and get a Sleep Guard. Now go back and head South (First door right after you exit this room), then down the stairs heading North. Go through another red corridor North, turn West, then North again, crossing another red corridor. At this point someone will comment about the maze-like structure of this place. Continue NorthEast and enter the first door to the NorthWest to get a Black Snake. Head back and continue fighting 2 Gebler Guards, then open the door to the East. Get the Panalphasol, save your game, then go back to the door near you to the North. Go down the stairs and exexute the manual scan, then go back to the room where you found the Black Snake and use the computer to reset the emergency level. Go back to the locked door heading South. Activate the computer at the SouthWest (Skip this if Elly's with you). Open the next door to the South and some scenes will start. Check the reactor and after some talking, you'll fight Tolone and Seraphita.

Defeat Seraphita first since her attacks are stronger and she can steal your EP (You'll need it later). Either build your AP bar or use Elly's Ether (Water on Seraphita, Earth on Tolone). Heal yourselves and save after the fight and start leaving Zeboim. You'll watch more scenes and fight Id (The guy with the Gear that crushed Bart). This guy can take over 200 HP to one person in one attack! Have at least one person healing and unleash your best combos on him. After another scene, exit the Site to watch another scene aboard the Yggdrasil. Save your game and talk to Sig. He'll say Fei isn't at the infirmary, so head for the gear hangar where Weltall is to meet him. After some talking, you'll form a party lead by Billy, but without Citan or Fei, to fight Stein.

This battle is rather annoying, since you can't hit him during the first turns and he has lots of HP. After Billy's father helps, attack him with your best deathblows and watch out for fuel and HP until the end (He takes some damage of the party before he dies). After beating him, you'll watch some scenes and Fei will be back on the party. You can now check the Gear Shop for upgrades (They might be too pricy for now, but try to buy parts strong against Ether attacks). You won't be back on the main map for a while, so get ready to climb the Babel Tower.
