Initially the castle is under siege by Marauders, but once the invaders have been repelled it can be used as a player home. The castle is patrolled by Men-At-Arms, while a blacksmith lives on the grounds with his wolf-dog. Unbeknownst to the other occupants, some unwanted tenants have been sealed away deep below the castle.
Several unique upgrades can be purchased for the castle; an ancient Dwemer Forge that buffs your Armorer skill, a trophy room to exhibit hunting trophies, a wine cellar. In addition, an assortment of staff can be employed to serve you at the castle; a chef to prepare food and drinks, a maid, a vintner to create special wines that enhance fighting abilities, a combat trainer for sparring practice, a taxidermist to craft lifelike trophies for the great hall.
The add-on also introduces Nilphas Omellian, an apprentice merchant with 2,000 gold. He can be found inside the Merchant's Inn in the Market District of the Imperial City. He is generally the best merchant to sell weapons, armor, and clothing to.
- Defeat the attacking marauders and become lord of Battlehorn Castle, located in the Colovian Highlands west of Chorrol. The castle has private quarters, a grand dining hall, wine cellar, barracks, training room, and – most importantly – a few hidden passages and dark secrets. —Official Summary

- The add-on was originally titled "Dragonfire Castle" and its existence was rumored in summer 2006, more than a year before it was officially announced by Bethesda. The original name can still be found in the Construction Set, with the word "Dragonfire" being used in several editor IDs.
- Fighter's Stronghold is the only official add-on not to be included on the Knights of the Nine retail disk and consequently the only add-on available solely in English.

- This bug is fixed by the Unofficial Oblivion DLC Patches.
