The Long Game Quest Walkthrough
In a villa towards the south-west of Elis, on the island of Olympia, you’ll find that someone has been at work killing the residents. Investigate the area, paying particular attention to the kitchen where the hamper is, the table in the kitchen with the vegetables, and a note in the pantry behind the kitchen. With the proof needed, go out of the villa into the main street and turn right. In the villa that you’ll see there, you’ll find the merchant you’re looking for. After some intimidation, he’ll reveal the location of the antidote, so go to Fort Koroibos. This is in the north-eastern part of the Elis region and is heavily guarded, though the antidote is in a small hut high up near the braiser, in a small treasure chest. Return to Alkibiades to give him the antidote.
