This is a light mod that adds wages to the Imperial factions Blades and Legion, and the Great Houses Hlaalu, Redoran, and Telvanni. I made it for another mod but thought it could stand alone too.

Wages are initiated by speaking with the faction bursar, and are paid daily. They increase with your rank. If you are expelled the payments cease, and begin again if you rejoin.

The mod also adds a unique item: debt bonds. These are traded by the savant Okan-Shei in Ebonheart, and can sometimes be acquired new from Houses. They pay a fixed interest rate, but the market price can differ to the face value according to risk. Riskier bonds may miss payments, and may even default (which is not necessarily the end of them).

Make sure you speak to Okan-Shei about the details. There are 7 available, and he sells 5 of them.

There are relevant topics added to factions, and a couple of conversational quests regarding bonds.

This mod is probably more suited to a modded Morrowind that makes gold more scarce than in vanilla, and balances weapons and armor values. But you can easily change the values in the scripts to suit your own play.

My first mod. Cleaned with TESTool. Let me know of bugs.

How it works:
The wages are a simple global script triggered by a conversation and faction membership.
The bonds are slightly more complex, with the item having an attached script that refers to a global with random numbers to create percentage chance.
The interest rates are unrealistic compared to the real world, but I wanted them to be enough of an incentive in game time.
