In addition to the main time periods, there are ten hidden time periods in the Historia Crux that can only be opened when an item called the “Wild Artefact” is used.
The Wild Artefacts in the game are scattered through the different time periods. Some you will obtain automatically, while others will require Mog’s Moogle Hunt ability. For anyone who wish to explore the Historia Crux to its fullest and unlock the hidden secrets within; here are the list of the Wild Artefacts that are scattered throughout the game.
