I'm very happy with a few certain characters that made it into this banner, and no, not just Tibarn.
Fire Emblem Heroes (Japanese: ファイアーエムブレム ヒーローズ Fire Emblem Heroes) is a game in the Fire Emblem series released for iOS and Android smartphone devices. The game is sold under a "free-to-start" business model, where the base game itself is free but numerous purchases are made in the game itself to obtain orbs, which can be used to summon characters or be exchanged for useful items.
