Fighter's Stronghold gives you none other than your very own Castle, complete with a troop of knights to defend it, a secret treasure vault, a wine maker to brew special potions, a combat trainer to spar with, and even a taxidermist to fashion sculptures out of your most impressive kills.
On top of all that is the obvious joy of owning an enormous fantasy property, with sprawling dining halls, wine cellars, barracks, training rooms, even an ancient Dwemer Forge that increases your Armorer skill - much like the Alchemy table in Frostcrag Spire. Beat that, Grand Designs.
