A new trailer from Nintendo has revealed that Fire Emblem Heroes is expanding its roster with a brand new legendary hero tomorrow. Seliph: The Scion Light is coming to Nintendo's mobile battle game.

Fire Emblem Heroes' Seliph: The Scion Light legendary event runs from June 30 at 12 am PST through July 6 at 11:59 pm PST. The free-to-play tactical role-playing game is a spin-off of the Fire Emblem series, featuring a mixture of its most popular and beloved characters.

Seliph has a pretty long-ranging history, being the protagonist of the 1996 SNES Fire Emblem game Genealogy of the Holy War. He's an exiled prince, hidden away for his own protection at a young age as his homeland Agustria fell prey to an evil force. Seliph's journey in the game naturally saw him learning of his true nature and working to rid the land of darkness while claiming his rightful place on the throne.

Players should be excited to know that Seliph's arrival also means a number of returning legendary heroes will be available to gather. Those heroes include Robin, Lyn, Azura, Duma Yune, Sothis, Peony, Ced, Eleonora, Chrom, and Mirabilis.

This Fire Emblem event only runs for a limited time, however, so interested players should take advantage while they can.

Fire Emblem Heroes is available now for Android and iOS devices.
