NEW UPDATE:

I will be adding the merchant events this weekend (as well as other stuff I haven't quite planned yet.)

A big benefit to having a large court will be to attract people of interest to your court. These people might be religious refugees, scholars, artists, poets, adventurers, or merchants.

For now, I've mostly worked on adding merchants. There will be three different kinds of merchants: those selling exotic goods, those selling weapons and armor, and those selling books. The first group is further subdivided between various regions. You might get merchants appearing from China, or Arabia. Depends on the roll of the die, which is also weighted by how large your court is and where it is located.

These merchants will sell a wide array of items, though for now I don't intend on adding any artifacts as a part of this mod. It might be something to be done in the future. But most vanilla artifacts will be for sale, and I have also added MTA artifacts to this mod, so if you have that mod the merchants will sell those artifacts too.

A note on the price, unlike the base game, I did not use scaled wealth at all. I find scaled wealth to be a stupid concept. A Tier 4 sword costs 4000 gold. HIP allows you to borrow the money if you really want to buy it. In most cases you will have to.

The AI handles this through modifiers. It works well enough, and no longer will you see the treasuries of great emperors completely empty of artifacts.

How do you plan to incorporate the new courtier improvements Paradox has put into the vanilla CK2?

@Aegon2001

That change and the wonders change will have to be incorporated in some way. I was going to add more court interactions, I'm not sure how I can use the court changes they are adding. I'll have to play to find out.

As for the Wonders, they'll obviously add to court splendor. Will have to check that too.
