How to Travel to the Past Dimension

Preparing the Required Items

Before you can reach the Past dimension, you need to collect two key items from cold regions in the Overworld:

1. Explore snowy plains biomes to locate the surface structure known as Revahkeim, or delve into underground Nordic monster rooms.

2. Search the dungeon chests inside these structures until you find the Wooden Mask and the Dragon Forge book.

3. Keep both items in your inventory.

Entering and Returning from the Past

Once you have acquired the required items, prepare for dimensional travel:

1. Ensure the immediate area is completely safe. The transition will not work if hostile monsters are nearby.

2. Hold the Dragon Forge book while equipping the Wooden Mask into your head slot.

3. You will immediately be transported into the Past dimension, where you will find the ancient version of the Revahkeim structure.

4. When you are ready to depart and return to your original timeline, simply open your inventory and unequip the Wooden Mask. Doing so will transport you safely back to the Overworld surface.
