[e]

From the Quest Selection screen take Act II quest No. 6. Betrayer of the Horadrim.
Take the Waypoint in the Hidden Camp to the Path to the Oasis. You'll get a Checkpoint as soon as you materialise.
Go down the Path to the Oasis and into the Dahlgur Oasis
Go right hugging the edge of the map and take the first right. This is a small cul-de-sac with a waterfall and could be where Zaven appears. If not go straight back out and head north.
Hug the right edge of the map and eventually you will come to another identical cul-de-sac. This is the second location Zaven could be. He could be in neither.
If he is not, leave the game and Resume Game to appear back at the Path to the Oasis.

Special Notes:

You might consider only looking for the first spot he can appear in as that is so close to the Waypoint in the Path to the Oasis so it is very quick to see he isn't there and restart. You can see by the Dahlgur Oasis map that the spot further north is quite a trek and you'll be pestered by beasties on the way up too.
When you've found and saved Zaven the Mysterious Cave will open behind him and this is where you may find the Liquid Rainbow, one of the ingredients needed for the Staff of Herding. It will appear in a Mysterious Chest which has a possibility of spawning (doesn't always).

Finding the Cave

A route to the Mysterious Cave.

The cave is associated with a merchant named Zaven the Alchemist. The alchemist will be cowering in front of what looks to be a boarded up door inside the face of a cliff. He is besieged by monsters, and if the player kills them, he will get a blue exclamation point over his head, indicating that he has something to say. After speaking with him, he will open up his wares for sale, and also open the door the Mysterious Cave. Zaven sells dyes appropriate to the difficulty level at half price to thank the player for saving his life.

Alternate location.

The door, and the merchant, will only spawn on one specific map tile, and it is always at the southern tip of the zone. A general route, barring any unexpected randomosity, is pictured to the right. If Zaven and the cave do not spawn on this tile, nothing will replace it: the door will simply be barred, and there will be no monsters in the area. For farming purposes, the best way to see if the cave will spawn is for the player to head down the peninsula-shaped map tile and see if there are monsters present.

There is an alternate farming route, shown in the image to the left, but the secondary map tile isn't guaranteed to spawn, and there's no telling which of the two tiles, if any, will spawn the Mysterious Cave.

In either location, straddling the southern border of the zone is the fastest way to find the cave.

The Mysterious Chest

The chest will be within the first level of the cave. The cave is similar to the Cave Under the Well, however it is much larger and more labyrinthine in layout. It may take some time to stumble upon the chest, but it will have the telltale yellow glow as a Resplendent Chest would, although it is named "Mysterious Chest" and drops nothing other than the Liquid Rainbow.
