Hints:
One of the clues you should investigate is at the bottom of the crater.
Two more clues can be found near the road leading northwest.
Two other clues can be found near the road leading north.
Hints:
When you have examined all the clues then two places will be marked on your map - Poimenos Cave and Koiladi Farm. Visiting the cave is optional, as you will eventually end up at the farm anyway.
In the cave you will find a note that tells you to head to the farm.
Bloody Note
"Spread out, and keep looking for him! Once you've searched every corner and lifted every stone, we'll meet by the farm to make another plan."
Take down the pirates that have taken over the village and free the three tied up prisoners.
Approach a group of villagers and talk to them. You will learn from them that Barnabas has gone mad.
Once you are done talking to the villagers then Herodotos will join you. Together you will come to the conclusion that Barnabas is possessed by an artifact and that this must be stopped. You will have the option to answer Herodotos when he asks you how you will do this:
But what you answer will have little bearing on what happens next.
Hint:
Barnabas hid inside the Temple of Zeus. Go there. You can enter the temple unnoticed through one of the two openings located on either sides of the temple.
When you get inside, Alexios will ask Barnabas to hand him the artifact. You will have the opportunity to choose how you will explain to him why you want to do this.
What you choose only affects the way Barnabas will react but he will not give you the artifact and after a while he will summon some illusions.
First you will have to deal with ten illusions that will start to emerge and attack you.
When you do this three more, this time non-aggressive illusions of your friend will appear in the room. Approach each of them, talk to them and then assassinate them.
When you do that Alexios will repeat his request to Barnabas to give him the artifact. Barnabas still won't listen and you will get the choice how to take the artifact from him.
Either way, everything will end happily. Barnabas and Herodotos will return to the vacation home in the south and this quest will end.
Rewards: Legendary XP, Legendary Drachmae, Barnabas's Lost Eye Patch (Epic Head).
After completing this quest, you will be able to play the quest A New Horizon.
