Primordial Guardian Origo resides within the Arch of Origo Primordial Vault, guarding its secrets and an assortment of Legendary loot. The monstrous boss uses elemental attacks in combination with its flight to devastating effect. However, reaching the boss can be an even greater challenge, as it involves gathering three Vault Fragments, and defeating as many stages of enemies within the Vault. 

Borderlands 4: Primordial Guardian Origo Location

Primordial Guardian Origo is located in the Arch of Origo Primordial Vault, which is found in the Low Keys area of Terminus Range. To access the Vault, find the three Vault Key Fragments marked by large search areas in Cuspid Climb, The Pit, and Windspear

Once you’ve collected all three Vault Key Fragments, the general location of the Vault entrance will become visible on the map. Starting from the Heritage Opus Safehouse, you can cross the bridge to the north until arriving at the first active checkpoint. You can then glide across to a cliff with an Auger Shrine at the edge.

Head into the cave entrance along the cliff wall and interact with the altar there to insert the three Vault Key Fragments. The Vault will open, and the ‘Primordial Vault: Terminus Range’ side mission will begin in earnest. 

Inside the vault, you will face three increasingly difficult combat challenges against Seneschal Order enemies. After the third challenge, you reach a platform with two vending machines. The Primordial Guardian Origo lies ahead.
