Throbi Grobbi-Nutter became lord of Mount Brightstone (formerly Mount Gunbad) early on in my campaign and he has helped bankroll my conquests ever since.

Mount Gunbad has a gold mine and a unique building called the Brightstone Mine that gives you a shitload of gold and increases your trade agreements by 10%.

I built every building that would provide gold and sent every agent with income traits and income banners there. Throbi got all the best income banners I had and he was very kind and released all the rebel armies he caught. This lead to him becoming the richest dwarf in the Karaz Ankor and Mount Brighstone becoming the shining beacon of Dwarf prosperity and resurgence!

Hard difficulty. Mods that I use that effect this - 10 building slot provincial capitals, Economy & income (Including Chaos), Better Trade, [Tier 4 minor Settlements](http://steamcommunity.com/sharedfiles/filedetails
