—Chrom explaining about Plegia to the Avatar.
Plegia (ペレジア, Perezia in the Japanese version) is a country controlled by a theocracy devoted to the Fell Dragon Grima.
Unlike its easterly neighbor, Ylisse, Plegia worships the Fell Dragon Grima as the god of annihilation. This leads to a conflict between the two nations for their worship of different dragons which lasted for nearly 1000 years. Plegia is ruled by their king, Gangrel, but his power affects only some of the nation. The other portion is ruled by a religious sect, the Grimleal, a cult that worships the Fell Dragon. Despite being a theocracy, only a minority of citizens worship Grima, although everyone, even the rulers such as Gangrel, are forced to pay lip service to the Grimleal.
Despite its desert landscape, Plegia has a bountiful navy and a large treasury, which Chrom borrowed from after the defeat of Gangrel.
Like all countries of the realm, Plegia was founded during a period known as "the Schism", a somewhat vague event in the time between Fire Emblem: New Mystery of the Emblem and Awakening. After the defeat of the Fell Dragon, Grima, Plegia stole a gemstone of the Fire Emblem, the black gem Sable. This was because the Fire Emblem was a part of the downfall of the Fell Dragon, and the Grimleal wanted to prevent it from being reassembled. A short time after the fall of Grima, the Grimleal was formed, and took control of Plegia. Because of the Grimleal working for Grima's resurrection, their Naga worshiping neighbors of Ylisse began a war with the Grimleal in Plegia.
Though the effect of the war on Plegia isn't fully known, it is said war was particularly more brutal, the realm of Ylisse was nearly destroyed as a result, but the war was abruptly ended when the previous Exalt of Ylisse suddenly died. With the daughter of the Exalt, Emmeryn, in power, all Ylisseans were withdrawn from Plegia, thus ending the war with the Grimleal. Ylisse eventually recovered and moved on from the war, while the Grimleal seemed to have been undamaged.
Later Plegia, led by Gangrel, desired to take over the continent as part of his plan to fight against Walhart's Valm empire. Turning the country into a religious state and improving both the military and economy, Gangrel eventually authorized raids on the Ylisse and Ferox to instigate a war between the three nations. This led to Chrom's Shepherds fighting back.
Though initially on the verge of victory during the war against Ylisse, Emmeryn's death has caused massive rebellion and desertion across the Plegian army, with only those close to the king remaining.
After Gangrel is taken out of power after his defeat at the Border Wastes, the country is thrown into chaos until Validar replaces him as the new ruler, further extending the Grimleal's influence on the land. Due to Walhart's conquest hindering their plans, the Plegians offers not only a vast amount of ships to Ylisse, but fully funds the campaign as well, in hopes of using them to prevent his success, with Excellus being used as a back-up plan to destroy the empire within. Validar attempts to resurrect Grima at the Dragon's Table, but fails and is killed in battle. However the Grima of the Future manages to resurrect the Grima of the present by sacrificing many citizens to Grima. However both Grimas are killed by the Shepherds along with the remaining Grimleal.
It is unknown who becomes the new ruler after Grima's banishment/death, and the destruction of the Grimleal. However, if Gangrel S-Supports the female Avatar, their conversation suggests that he becomes their leader again, with the Avatar keeping him in check.
