I heard you were in need of an Essyrni! So, today, I present to you:
Kil'karic!
Kil'karic is from a race native to the Essyrn Deserts and is a travelling Merchant who loves to spend time in Essyrn, and around there. He's generally sarcastic, and very "borrowy". He'll take what he thinks no-one will miss or what everyone will want, and will always try and haggle the highest prices for worthless items. If he were to have a store, it would mostly be filled with junk, which, while it may be helpful in some cases, would most likely just clog the player's inventory.
I might suggest an alternative use as perhaps a basic fetch quest character? He wouldn't exactly ask for much, but what he would have, he would again sell later at a stupid price.
Just there for a bit of a laugh really.
