Dar'marash is a merchant follower I made on Skyrim to help me with the loot.
You will be able to find him at the entrance of Markath, and he will be willing to follow 
you if you help him a bit.

This follower starts with only ragged clothes on the body, so you can change his outfit at will to anything you want.
Want to give him merchant outfit? You may do so.
Want him to use heavy plates? You can do so aswell.
Or, want him to cosplay as a bandit? Feel free to.

He also contains an internal storage which you can use to place and remove loot inside.
That internal storage has no weight limit, and you can use an extra interaction with 
Khajiit Caravans, to instantly sell all the loot in it.
Do notice that the loot sold to the caravans will disregard enchantment value change and stuff, because 
Bethesda. So, sell enchanted items directly with npcs yourself.

And, he also functions like an additional follower to you, which can help you in combat, and also can split the head 
of foes with his great axe.

The mod does contains a few flaws by the way.
One of the flaws, is that his dialogues are not voiced, so I had to measure the time a dialogue would last with an empty noise.
The other flaw, is that I didn't actually knew how the dialogue system works, so to speak to him, first you'll need to say "Hello." to him.
