The fourth game in the Fire Emblem series, released in 1996 for the Super Famicom.
The game is divided between two generations, with the First Generation featuring Sigurd and his exploits on the continent of Jugdral, as he unravels a conspiracy against the Kingdom of Grannvale. The Second Generation focuses on Sigurd's son, Seliph, who leads a resistance against the now corrupt Grannvale Empire, orchestrated by the Cult of Loptous.
While obscure, it is generally considered one of the best Fire Emblem games ever made, due to its engaging story, interesting characters, and vast worldbuilding.
