Do you hear that energetic whirring in the distance? It’s positively radiating. That’s the sound of Book V kicking into high-gear for the Fire Emblem Heroes game!
The latest update to the Fire Emblem Heroes smartphone saga* is arriving tonight, and it’s delivering a blast of steampunk-inspired energy to this classic tale of sword and sorcery. The realm of Niðavellir has discovered a way to fuse magic and science into something they call seiðjárn, and it’s safe to say you’ve never seen a realm like this before in the Fire Emblem Heroes universe! For a glimpse at the unique flavor Book V is adding to the game, check out the animated cinematic trailer:

In addition to some intriguing characters, Book V also introduces new mechanical armor, known as Gullinbursti, which is used by the people of Niðavellir to do battle. If you’re eager to see some of this new content in action, even novice summoners can jump right into Book V’s story. By completing Chapter 1 of Book V, you will also earn a new Mythic Hero for free: Reginn, princess of Niðavellir.
We hope you’ll take advantage of all the Book V-related events and bonuses. If you log in on 10 different days during the active period, you can receive up to 20 orbs. You can also earn Aether Stones by clearing “Book V Begins” quests while they’re active. Aether Stones can be used to unlock new bonus structures which will be added to the Aether Resort. A special castle design themed after the world of Book V will be sent to all summoners, too!
You’ll also want to keep your eyes peeled for New Heroes from the Fire Emblem: The Sacred Stones game, including Duessel, Caellach, Selena, Knoll and Natasha!
