The Sacred World

The Sacred World is the tenth paralogue of Fire Emblem Heroes.

Part 1: A Lecture Fit for Royalty
You will have 4 units on your team. You will also have 4 opponents: Amelia, Seth, and 2 Emblian Bow Fighters.

In order to clear this stage, you will have to defend your units for 7 turns. However, unlike the other chapters, none of the enemies have Embla's Ward, therefore you can clear this stage even before 7 turns have passed. For the first 4 turns (including the sixth turn), enemy reinforcements will appear.

Part 2: The Heirs of Freila
You will have 4 units on your team. You will also have 4 opponents: Innes, Tana, an Emblian Sword Fighter, and an Emblian Green Mage.

In order to clear this stage, you must defeat all the enemies in 4 turns. If you did not defeat them after 4 turns have passed, you automatically lose and the game is over. This objective is exclusively on Lunatic mode.

Part 3: The Silver Knight
You will have 4 units on your team. You will also have 4 bosses: Amelia, Seth, Innes, and Tana.
