In Winter Ember, you play Arthur Artorias on a quest for vengeance. You will face many obstacles on your journey, including the door to the Cart Room. A nearby note tells you that you need the Guard Captain's Key to open it. This may leave you wondering where to find the Guard Captain's Key in Winter Ember.
The Guard Captain's Key can be found in a secret safe behind a painting within the Guard Captain's Office in Winter Ember. You must go through the Warehouse and reach the top to find the office. Use the upper planks on the second floor to get around the locked stairwell door. You will reach the roof and, eventually, the Guard Captain's Office.
Where to find the Guard Captain's Safe?
The Guard Captain has hidden the Cart Room Key inside a secret safe. You find this safe hidden behind the painting directly in front of the office desk. Interacting with the painting will remove it and reveal the safe. This safe can be opened with a secret combination.
How to open the Guard Captain's Safe
The combination to the Guard Captain's Safe is 545. You can see this number to the right of the safe, where the green panel depicting 545 is getting electrocuted. Enter the combination, swipe the key, and return to the Cart Room to proceed.
