“After losing Agusty, King Chagall moved his royal court north to Madino. Keeping his word with Eldigan, Sigurd did not pursue him. While the troops rested at Agusty Castle, Sigurd worked to fulfill his promise to Eldigan. He persisted in negotiations aimed to return administrative control back to Agusty. However, the directive from Belhalla to 'maintain a presence', and 'govern the people', never changed. In a half year's time, the officials dispatched to Agustria became exceedingly reckless, and began to abuse the power they were entrusted with. The discontent of the Agustrian people slowly began to take root. Before long, a new conflict arose giving Sigurd great cause for concern. Chagall had been arranging a military force at Madino poised to challenge Sigurd in an attempt to regain control of the capitol at Agusty. Meanwhile the notorious Orgahil Pirates north of Madino positioned themselves to take advantage of the ensuing chaos. Sigurd had strict orders from Belhalla to hold Agusty Castle at any cost. The ensuing conflict weighed heavily on Sigurd's heart. In addition, Eldigan had troops stationed at Silvail Fort southwest of Madino. The battle on the horizon was gearing up to be a true test of one's friendship and loyalty. All of Sigurd's attention was now focused on the looming threat at the northern reaches of Agustria... one that could very well change the course of history.”
Lionheart Eldigan (Lion King Eltshan in the Japanese version) is Chapter 3 of Fire Emblem: Genealogy of the Holy War.
The difficulty of this chapter can be greatly reduced by doing several things. First, make sure to bring Raquesis. Talking to Eldigan with her will not only give her the Earth Sword, but will also make Eldigan permanently leave the battlefield, both of which are highly recommended outcomes. Another aspect of this chapter that may catch new players by surprise is that the bridge connecting the northern island with the rest of the map will appear just north of Madino Castle the turn after Silvail Castle is captured. It is recommended to have at least some units around Madino Castle before capturing Silvail Castle in order to facilitate the rescue of Briggid, Tailto, and Claud from the Orgahil Pirates.
