Battlehorn Castle stands as the premier residence for warrior-class characters in The Elder Scrolls IV: Oblivion. Located in the Colovian Highlands, west of Chorrol at the end of the Black Road, this massive fortress is part of the Fighter's Stronghold official plug-in. Unlike the modest homes in the Imperial City or the dark depths of Deepscorn Hollow, Battlehorn offers a blend of military prestige, functional utility, and deep-seated lore secrets that remain relevant even in the late stages of a playthrough.

The Siege of Battlehorn Castle

The journey to ownership begins as soon as you approach the castle's perimeter. Unlike other properties that require a simple purchase from a Count or Countess, Battlehorn must be won through steel and strategy. Upon arrival, you will find a desperate battle in progress. A group of marauders is laying siege to the castle, having already struck down the previous owner, Lord Kelvyn.

To secure the deed, you must assist the remaining Men-at-Arms in repelling the invaders. The attacking force typically consists of a diverse group of marauders, including a warlord, a battlemage, and several archers. It is advisable to prioritize the battlemage first to prevent area-of-effect spell damage from thinning the ranks of your future guards. Once the last marauder falls, speak to the surviving Men-at-Arms. In gratitude for lifting the siege, they will present you with the deed to the castle, though the structure itself remains in a state of disrepair.

Essential Upgrades and Where to Find Them

Acquiring the castle is only the first step. To restore it to its former glory, you must visit Nilphas Omellian, a Dunmer merchant located at The Merchants Inn in the Imperial City Market District. Nilphas holds all the contracts for refurbishing the various wings of the fortress. In the Remastered editions and updated mod lists, the costs for these upgrades typically hover around 1,500 to 2,500 gold per section, with the total investment exceeding 20,000 gold for a fully functional stronghold.

The Master Bedroom

This is more than just a place to sleep. Upgrading the private quarters transforms the upper floor into a luxurious suite. Beyond the aesthetic improvements, this upgrade employs Rona Benanius as your personal maid. Rona provides a unique service: she can supply you with food and drink (including any vintages currently stocked in your wine cellar) and can even accompany you outside the castle walls as a follower, though her combat capabilities are limited.

The Library and Study

For the scholar-warrior, the library upgrade is indispensable. It fills the shelves with a wide array of Cyrodilic literature. More importantly, it adds several valuable skill books, including History of the Fighters Guild (Heavy Armor) and Heavy Armor Repair (Armorer). This area also contains a desk and safe storage containers that do not reset, making it the perfect place to store rare artifacts and soul gems.

The Training Area

Located in the basement, the training area upgrade provides the essential infrastructure for a knightly order. You will gain access to a sparring partner, Shagrol gro-Uzug. Shagrol is an essential NPC, meaning he cannot be killed in combat, allowing you to practice weapon skills or destruction magic indefinitely. The room is also stocked with various weapons and armor pieces that serve as decent backup gear for followers.

The Dwemer Forge

The Dwemer Forge is arguably the most functional upgrade in the entire DLC. Once purchased (which usually requires at least one other upgrade to be active), the old smithy in the courtyard is replaced with an ancient Dwemer design. Standing near this forge grants the "Dwemer Fire Heart" buff, which provides a constant +15 boost to the Armorer skill. This is particularly useful for players who want to repair their own enchanted gear but haven't yet reached the Master level in Armorer.

The Knights of the True Horn

By purchasing the Barracks upgrade, you revive the ancient order known as the Knights of the True Horn. This brings Castellan Athon and two additional Men-at-Arms to the castle. These guards will patrol the ramparts and the interior, giving the castle a lived-in, secure atmosphere. Castellan Athon serves as the commander; should any of your guards fall in battle while following you, Athon can provide replacements for a small fee. This ensures that your private army is never truly depleted.

Hidden Secrets: The Grotto and the Lich

Battlehorn Castle holds secrets that far exceed its surface-level utility. Within the basement training area, there is a hidden mechanism behind one of the archery targets. Activating the unlit candelabra reveals a secret passage leading deep into the Battlehorn Grotto.

This subterranean cavern is the final resting place of Lord Kain and his treacherous advisor, Arielle Jurard. Lord Kain has been raised as a unique skeleton, while Arielle has transitioned into a powerful Lich. This encounter is one of the more challenging "hidden" boss fights in the game.

Strategic Loot from the Grotto:

  • Dragonsword of Lainlyn: A unique enchanted longsword held by Lord Kain. It features a fire damage enchantment and grants the player the "Dragon Breath" spell while equipped.
  • Lord Kain's Shield: A heavy shield with a constant-effect Light enchantment, useful for cave exploration.
  • Varla Stones: Three Varla stones can be found scattered throughout the grotto, essential for recharging multiple enchanted items at once.
  • Lord Jaren’s Journal: Found in a secret vault accessed via the library, this journal provides the backstory of the castle’s fall and clues to the grotto’s location.

Domestic Services: Wine and Trophies

One of the unique aspects of Battlehorn is the ability to produce custom items through your staff.

The Winemaker: By upgrading the Wine Cellar, you hire Talan. If you provide him with specific alchemical ingredients, he can brew unique vintages that offer potent buffs. For example, providing him with Bergamot Seeds and Foxglove Nectar allows him to craft Argonian Bloodwine, which provides Resist Poison and Water Breathing. Each batch takes 24 hours to ferment.

The Taxidermist: Melisi Daren, the resident taxidermist, resides in the East Wing. If you bring her pelts or creature parts (such as Minotaur Horns or Ogre Teeth), she will create stuffed trophies of the creatures you've defeated. These trophies are then displayed in the Great Hall, serving as a visual testament to your character's prowess across Cyrodiil.

Safe Storage and Inventory Management

A common concern for players is whether their loot will disappear if left in a castle container. In Battlehorn Castle, the following containers are verified as "safe" (they do not respawn/reset):

  1. Private Quarters: Every chest, wardrobe, and drawer in the master bedroom and library area is safe for long-term storage.
  2. Great Hall: The rounded chests near the entrance to the north tower and the lectern in the trophy room.
  3. The Kitchen: The sacks and the covered pot are safe, though the barrels are not.
  4. The Grotto: The chest submerged in water (requires Arielle Jurard's key) is a safe, high-capacity container.

Players should avoid storing valuable items in the barrels in the basement or the courtyard, as these are prone to resetting their contents every few in-game days.

Comparison: Why Choose Battlehorn Over Other Strongholds?

When comparing Battlehorn to other DLC homes, its advantages are clear. Unlike Frostcrag Spire, which is heavily geared towards mages and lacks a natural "lived-in" feel, Battlehorn provides a community of NPCs. Unlike Deepscorn Hollow, it is located in a central, accessible area of the map rather than the remote marshes of Blackwood.

The inclusion of the Dwemer Forge gives it a mechanical edge for any character who uses physical weapons and armor. Furthermore, the combination of a trainer, a merchant (Nilphas eventually visits the castle in some versions), and multiple followers makes it the most comprehensive base of operations for a player who enjoys the "Lord of the Manor" roleplay.

Final Recommendations for New Owners

If you have just acquired the deed, focus your gold on the Bedroom and Dwemer Forge first. The bedroom provides a bed for leveling up and a maid for supplies, while the forge ensures your equipment is always in top condition. The Grotto should be explored only when you are at least level 15-20, as the Lich Arielle Jurard scales with the player and can be devastating with her high-level destruction spells.

Battlehorn Castle is more than a mere house; it is a dynamic piece of Cyrodiil's history. By investing the time and gold to fully upgrade the fortress, you secure not just a roof over your head, but a legacy as the true Lord of the Colovian Highlands.
