It's impossible to give a definitive answer to who "trades artifacts" from the North, South, East, and West without more context. Here's why:

* "Artifacts" is very broad. It could refer to anything from ancient pottery to modern technology.

* "Trade" can mean different things. Are we talking about legal, black market, or even just the transfer of objects within families or communities?

* "North, South, East, West" are vague geographical terms. Do we mean specific continents, countries, regions, or something else?

To give you a better answer, you need to be more specific about:

* What kind of artifacts are you interested in?

* What timeframe are you interested in?

* What kind of trade are you interested in?

* Which specific regions are you referring to?

For example, you could ask:

* "Who traded ancient Egyptian artifacts in the 18th century?"

* "Who trades modern art on the black market?"

* "Who trades traditional clothing within indigenous communities in the Amazon rainforest?"

Once you provide more details, I can help you understand the complex world of artifact trade!
