Talk with her to know what you must do next. you will be given the last Serpent Tooth for Isle of Crypts. You can drop all Buckets and your 3 Automatons. You don't need them anymore, now you have your old Companions back.

 * Dupre with Water of Discipline
 * Shamino with Water of Ethicality

Before going to Isle of Crypts, you need to take all 3 Blackrock Parts and at last one of Serpent Artifacts (Either the Serpent Crown or the Serpent Staff) with you. You will need it on Isle of Crypts. Go there over the Dark Path.

Isle of Crypts
The Entrance is on the other Side of the Mountain at (12N, 44W). There are several Spider Silk in entire Cave. At the Room with 2 Paths, take the South one, then the North to find more Spider and  Spider Silk. Go South and place any Blackrock Part you have on the Table to open a secret Wall to the South to pick a Chest for Transcribe Scroll,  Juggernaut Hammer and a Scroll. Go back and take back the Blackrock Part.

Go Northwest, North (ignoring the Room West as it has only some Spider) to another Room with Coffins. Push the Button West of the Book to open a Path North. Make sure the Blackrock Balance Serpent is in your Backpack or else you can't be teleported in the next Location. Kill the Mummy and continue West (The Coffin Northwest has an  Undead which attack you if opened). The Corpse by 2 Coffins have tons of Reagents. Continue and press the Button by the Doubledoor. Open the Door and destroy 4 Traps at every Corner. Continue your Path until the Path ended. Kill the Mummy and get the Scroll off his Body. Go back to the Room with the Pedestal and place the Scroll on the empty Pedestal. You will get teleported again to a Room with Debris and destroyed Books. Read the Book to learn more over History. After finished reading you will then get teleported again. Go West and kill the Skeleton Dragon and click on the Button left of the Black Serpent to Dispell the Field to get the  Chaos Serpent Eye. Now click on North Wall to open a Path to a Teleporter. Step on it to reach the Tomb with the Order Hierophant. Open the Coffin and cast Summon Shade on the Mummy in the Coffin. You need at last one of the 3 Serpent Artifact (Staff, Armour or Crown) in order to talk with him). He tell you how to restore Balance and you need the Serpent Staff, Serpent Armour and Serpent Crown. He will tell you where to find, if you didn't have it in your Backpack already. He also tell you what happened with the Great Earth Serpent and lastly that you need to reunite the Chaos Serpent first before restoring Balance, but to do that you need to find the Chaos Hierophant, since only he know how to do that, then he disappear into Void.

Chaos Hierophant
Go back to Temple of Tolerance and talk with Sethys. He know where Chaos Hierophant last Restplace is. Take him outside and he will tell you where you can find it. After his Death, take the Eye of Serpent from his Body. Go to Temple of Enthusiasm and cast Summon Shade on the Corpse to call the Chaos Hierophant. He will explain some of the History in more Details and tell you how to restore Chaos Serpent. He tell you that you need 3 Prisms with Banes inside and any Blackrock Serpent to perform the Rite in Skullcrasher Mountains, then he too vanish in the Voids, but he will leave a Scroll to you, in case you need to know what to do again. He also give you a Riddle for which you don't know the Answer, so you need to talk with Xenka again to solve the Riddle.

Sacrifice
Go back to Monk Isle and talk to Xenka. She will tell you that only a sacrifice from someone in your Party will restore the Imbalance and you lost by drawing the shortest Straw. Go to Monitor and try to sacrifice yourself by pulling the Lever on Crematorium Machine and Dupre will stop you and do it himself. Take Dupre's Ashes and go back to Monk Isle to recruit Gwenno to replace Dupre. Now go to ../Shrine of Chaos/ to reunite the Chaos Serpent.

Note: if Xenka does not give the option to talk of 'sacrifice' after the chat with chaos heirophant, you've got the Xenka bug - it can be fixed by going back to furnace to the room you picked up the serpent staff. Try putting the staff back where it was, walking around all of the room and then picking it up again. This should activate the flag egg to progress the dialogue options.

Inn of the Sleeping Bull
Everyone is dead, except Wilfried, who can join you and also train you and your Companions, however once he is hurt he will leave the Party.

Monitor
Like Inn of the Sleeping Bull, everyone but one is dead. Harnna is the sole Survivor in Monitor. Flicken's Body has 99 Bolts and Luther has a Key which open the Door to List Field. Since Brendann and Shazzana have died, nobody can train you or your Companions in Dex.
