Approaching the Domus Aurea

After freeing Scylla you must break the seal to the second half of the Sea of Bygone Eras. This is done by hitting the button prompt on screen within the countdown when it appears.

If a prompt is missed, you will be taken back to the start of the current. The challenge can easily be restarted by just talking to Scylla again though!

• Completing this challenge will light up the rest of the Sea of Bygone Eras map.
