Talk to Hermes
Your first task is to find and talk to Hermes. You can find him in Minos’ Faith, at the exact location shown in the map below.

You will find guards all over the area. Kill them first.

He will follow you all the way. Get to the location shown below.
When he stops, talk to him.
During the conversation, I chose to take him to Persephone myself.
Escort Kyros to the drop-off
Now, grab your horse and follow Kyros to the drop-off point.
Kill the mind-controlled humans
On the way, you’ll encounter a few humans. Kill all of them.

Kyros will then follow you on your horse.
Get him to Hermes and the quest completes here.
You’ll get a breastplate as reward.
