Should I Join the Dark Brotherhood?

When It Makes Sense

• Good fit: You want a stealthy assassin playstyle. The Dark Brotherhood questline is built around infiltration, silent kills, and subterfuge. If your character already invests in Sneak, One-Handed, Archery, Illusion, or Alchemy, the faction’s contracts and final rewards align naturally with those skills and make the missions feel cohesive rather than forced.
• Good fit: You are interested in unique faction rewards and a memorable story. Membership grants access to items that cannot be obtained through other questlines, including the Blade of Woe dagger, the Shadowmere mount, the Windshear scimitar, the Ancient Shrouded Armor set, and the Spectral Assassin summon power. The narrative—involving the Night Mother, the Black Sacrament, and the role of the Listener—is also one of the more distinctive story arcs in the game.
• Good fit: You are comfortable with an antihero or villain roleplay. Joining means accepting contracts to murder named NPCs. If your playthrough treats the Dragonborn as a pragmatic killer, a servant of Sithis, or simply a mercenary, the faction’s tone and choices will feel consistent with your character.

When You Should Avoid It

• Warning sign: You are roleplaying a lawful-good or heroic Dragonborn. The Brotherhood’s core activity is paid assassination, often of non-hostile characters. If your character protects innocents, serves the Divines, or generally avoids murder for hire, the required kills will undermine that roleplay and may feel out of character.
• Warning sign: You want to experience the “Destroy the Dark Brotherhood!” questline. Once you join the faction, this alternate path becomes unavailable in the same playthrough. The destroy route lets you assault the Sanctuary, kill the assassins, and work with Commander Maro in a very different storyline.
• Warning sign: You prefer not to break other side quests. Several Dark Brotherhood targets are also quest givers or characters involved in minor questlines. Killing them can make related quests impossible to complete, which matters for completionist players or those trying to see all available content.

Pros and Cons

Pros

• Powerful and unique gear. Rewards include the Blade of Woe (a dagger with a useful absorb-health enchantment), the unbreakable Shadowmere, the Windshear scimitar with a stagger effect, the Ancient Shrouded Armor with bonuses to sneaking, and the Spectral Assassin power. These items favor stealth and combat builds and remain useful for much of the game.
• Substantial gold income and a structured questline. Contracts pay well, the faction storyline has a clear progression from recruit to Listener, and successful completion leads to the Dawnstar Sanctuary headquarters and optional Sanctuary upgrades such as a torture chamber.

Cons

• Locks out an entire alternate questline. Joining prevents you from playing the “Destroy the Dark Brotherhood!” quest on the same character, so you must choose which story experience you want for this playthrough.
• Moral cost and potential quest breakage. You will be required to kill named NPCs, some of whom are tied to other quests or to local communities. This can create conflicts with a heroic character concept and may block side content.

Decision Checklist

• Is my character concept compatible with paid assassination and working for Sithis?
• Do I want the unique rewards enough to give up the “Destroy the Dark Brotherhood!” alternate questline?
• Am I willing to kill targets that may be tied to other side quests, and have I checked whether those quests matter to my playthrough?
• Would I rather experience stealth content through a less murder-focused faction, such as the Thieves Guild?

Alternatives to Consider

If the Dark Brotherhood does not fit your character, several other options remain. The Thieves Guild in Riften offers stealth, infiltration, and a criminal faction storyline without mandatory assassinations of named NPCs. The Companions provide a combat-focused warrior path with werewolf mechanics, while the College of Winterhold focuses on magic. If you specifically reject the Dark Brotherhood, you can instead undertake the “Destroy the Dark Brotherhood!” questline, which begins after the Aventus Aretino quest and allows you to eliminate the faction entirely. Finally, you can ignore both paths and still complete the main story, the civil war questline, and most side content.

Final Recommendation

Join the Dark Brotherhood if you are playing a stealth or assassin character and want exclusive rewards, a darker storyline, and a structured contract system. Avoid it if you are roleplaying a hero, want the “Destroy the Dark Brotherhood!” experience, or are concerned about killing quest-related NPCs. Because the choice is mutually exclusive within a single playthrough, the safest approach is to make the decision on a separate save file or a new character if you wish to experience both sides. There is no real-world risk, so choose the path that best serves your enjoyment and roleplay goals.
