The "Lair of the Harpy" story mission in Borderlands 3 begins with Aurelia Hammerlock inviting the vault hunter to Jakobs' family mansion. Aurelia does not want the vault hunter on Eden-6, and claims to have a a fair offer that will be mutually beneficial. Sir Hammerlock, Aurelia's brother, knows that the invitation is a trap.

Jakobs, though, does not care about her intentions. He is confident that he can get the Eden-6 Vault Key if he and the vault hunter stick together — and in the end, he's not wrong. Following the steps in this guide, gamers will have no problem fending off Aurelia and her minions to secure the Vault Key.

Getting To Jakobs' Manor

Aurelia is supposedly located at Jakobs' Manor. Jakobs he has a good idea of where his father may have hidden the information they are looking for, and asks the vault hunter to act as a distraction.

The Manor is on the southwest end of the map. It is quite a walk from the spawn point, so using a vehicle is recommended.Before heading in, players can hit the vending machines for some supplies. At the camps before reaching the manor, there will be a horde of enemies to fight. After dispensing of the enemies, gamers will need to use the Servant's Lift to the north.

From there, the player should enter mansion and walk up the stairs. On the second floor the double doors on the right lead to the foyer. There, Troy and his enormously long mechanical arm will be waiting. Thankfully, Jakobs appears to protect the vault hunter, luring Troy away. While Jakobs is fighting, players will need to make their way to the theatre and find the trap door.

Getting To The Cabaret

Once the cut scene is over, Fanatics and Goliaths will flood into the room. Enforcers and Sluggers will spawn in not too long after the others. The path to the Cabaret is straight through the door in front of where players spawn in, then straight through the next room as well.

There are plenty of crates to loot in the area, and the blue indicator will act as a guide to the lower levels. As soon as players get to the archives, they will need to hop down to the lower level and go up the stairwell in the back right corner of the room. Here, watch out for the Badass Goliath, as they have a huge health bar.

At the top of the stairs, there is a hole in the wall that leads further into the mansion. This will take the vault hunter into the Ancestor's Hall. At the end of the hall lies the Theatre, and a telepathically morphed Goliath.

Fighting Billy The Anointed

Troy decides to utilize his new powers by transforming a Goliath into a massive purple monster with a human head. Billy the Anointed is a big boy, and has a lot of health as a result. Movement is key in the fight against Billy, as he likes to perform a melee and jump slam attack. If the boss fires the red skulls, shoot them or they will follow the character until they make impact.

Billy's little head is vulnerable, so vault hunters should aim at it for critical hits. He will also release horizontal beams of light. To avoid them, jump right before they reach the player's character model. While he may be a powerful foe at this point in the story, constant movement and critical hits are enough to defeat the boss. At low health, Billy will go invisible and transport throughout the loop. Keeping an eye out for those horizontal beams is especially important at the end of the fight.

Finding The Keycard

Once Billy has been defeated, gamers will need to head up the stairs to the technician's booth to gain access to the secret study. Here, players will find three latches which move props on and off the stage. To complete the puzzle and open the door, all three props must be in the correct positions on the stage. The posters in the booth provide the player with clues to the combination.

Searching The Hidden Room For Records

The vault will open on the stage floor once the correct password is entered. The vault hunter can then make their way trough the den and into the bedroom, where the skull on the bookcase will open yet another secret door.

In the hidden study, the "records" referenced are cleverly hidden in a vintage record sleeve. Grab it off the wall and the wall will break down, opening a passage. There, a loot box can be found with a couple of guns in it for players to grab.

After looting, head down the ladder to exit the manor. Jakobs will want to take a look at the item once players fast travel back to Floodmoor Basin. As an additional reward, vault hunters will get the Whispering Ice Grenade Mod, $4,000 and 15k XP.
