Etesias' Olive Grove (Location)
A treasure-holding olive grove in Haueris Nome.
Heavily guarded as olive groves go, but you can sneak in from the western door without being spotted (murdering farm guards for loot seems little low for a Medjay).
The treasure is in a red chest inside, next to a letter from the Nomarch.
Opening the chest completes the location, but it's also loud enough to draw guards, so be ready to move.
