IV: Light's Sacrifice (四:迫る亡失, Yon: Semaru Bōshitsu lit. 4: The Lost Approaching in he Japanese version) is Xenologue 18 of Fire Emblem Fates.


After being defeated by some of the Hoshidan children, Siegbert and his group decide to stop and rest a bit. However, after some persuasion by Soleil, he decides to go to battle.

Elsewhere in a Deeprealm swamp, a group of Vallites chase after Forrest's group when they decide to retreat. As Forrest's group also leaves, Forrest spots Siegbert but hopes that he can hold them off. Siegbert thinks he saw Forrest, but unsure if his eyes were playing tricks on him, decides to press on.

At the Great Wall of Suzanoh, Siegbert and his group fight off the Vallites when Forrest and his group arrive. The two work together to question the invaders, eventually defeating them in battle.

After the battle, the Hoshidan children square off against the Nohrian children. Male Kana tries to fight back but his Grim Yato is not strong enough against female Kana's Blazing Yato. Siegbert offers Kana his assistance, and the Grim Yato reacts with Siegfried, turning it into the Shadow Yato. Kana uses it to attack female Kana, and for a few seconds, shows the true identity of both sides, confusing and surprising them before the illusion resets.

Both Kanas then turn into dragons. Siegbert and Forrest try to calm down male Kana, but are only stopped when Shigure steps in. The group finds themselves in Valla, and Shigure directs them to a safer location before telling them everything.

At the hideout, Shigure explains that Anankos had put an illusion spell on them in an attempt to kill each other after his first attempt to kill both parents and child failed. He starts to explain that both the Hoshidan and Nohrian children come from different realms, and tells them that they thought that they were all in one realm. Shiro and Siegbert comment on the war on their side and are surprised to hear what had happened; Shiro says the Hoshidans won the war and that Xander and Elise died, while Siegbert says the Nohrians won and both Ryoma and Takumi died.

Due to the conflicting stories, Shiro and Siegbert decide it is best to separate, much to Shigure's worry as rather then working together, they are refusing to just like Anankos had planned.

This Xenologue is extremely similar to that of Chapter 23 of Conquest, in terms of enemy and player positions.

Most of the enemies can be easily taken down with Siegbert and someone who can pair him up with speed. Velouria will give him +2 Strength and Speed, so she is a prime candidate for Guard Stance. The enemies south of the moat should not be a particular problem to you. Siegbert can pretty much wipe out the Knights, Soldiers and Fighters by himself, while the rest of the group can go south to take care of the cavaliers at the forts. Just remember to give Percy the Pike-Ruin Club dropped by one of the Fighters.

If Siegbert is around the ballista the Nohrian children from Heirs of Fate 2 will arrive as allies. Have Siegbert talk to Forrest to have them join you, or let Forrest come to Siegbert instead, as Forrest's group will make towards your group until they talked to each other. AI Forrest will initiate the conversation himself during his turn if given the chance, so make sure to be in a good position to take on the next group of enemies first.

After Forrest talks to Siegbert, make sure you have a plan to take out Shiro's group coming out of the gate behind Hisame's starting position shortly after you end your turn. If you don't, you will easily get wiped out. Asugi and Shiro are probably the most difficult to take out due to their speed and carrying ranged weapons, but if you plan things carefully, you can prevail over them. In hard mode, Ophelia and Forrest should make quick work of Shiro in Attack Stance, as the former will debuff his avoid and resistance to magic damage. Caeldori is a safe one shot by Nina and the rest can be mopped up by the rest of your troops as you outnumber them by quite a margin. Taking out Asugi quickly also deprives most of the Hoshidan children of their attack stance partner.

At the top of the wall is another group of Vallites, along with female Kana paired up with Selkie. There are also two Archers, four Knights and Mitama surrounding them. To easily take them out, have Siegbert take out one of the archers on either side, while positioning him so that some of the nearby Knights will attack him. At the end of your turn, some of these Knights will have died, and on your next turn, run Siegbert down the staircase. The enemy will return to their normal positions and when done properly, should only result in a Knight, Kana, Selkie and Mitama being the only units left on the first section of the wall, so repeat this process until only Kana, Selkie and Mitama remain. After wiping out the goons this way, Siegbert can actually sneak over the wall into Kiragis section and start wiping it out by himself.

Siegbert and whoever he is paired up with can easily take out this supposed to be final final group easily. Have Siegbert attack the Spear Fighters; he should take them out in one turn. Once both are taken out, simply have him stand next to Kiragi and attack him; unlike in Chapter 23 where Takumi carried Point Blank, Kiragi does not carry it and will only use the ballista to attack (having 20 damage and 95 accuracy), so if the ballista hits Siegbert, he should only take 2 damage from it.

Enemy units will never use stairs, but will attack if Siegbert stands on the edge of the top most section if they have ranged weapons. Kana will be forced to use her Kodachi only dealing 3 damage to Siegbert, who will retaliate with sword lasers who should deal 22 damage in return (these number are taken from hard mode, so might differ on other difficulties), so after mopping up Kiragi this can be a viable strategy to kill Kana without having to worry about Grim Yato, the reinforments, or Selkie and her Beastbane ability. Siegbert will be able to easily take out the reinforcing dark mages with Siegfriend from the same position, while the reinforcing Cav, Selkie and Mitama should be easy pickings for the rest of your army, who at this point should use the stairs to climb to the top of the wall.

Distracting Kana might also give Nina an opportunity to raid the two treasure chests above, who contain a Dual Katana and a Levin Sword, however these pieces of gear are wholly unnecessary to beat the chapter, as Siegbert, your troops should be sufficiently geared up anyway, and can pretty much deal with the enemies atop the wall by himself, and can actually seen as bait to make the player go out of their way to acquire the treasue and thus expose their characters to enemy retaliation.

Chest Items

Enemy Reinforcements

  • This Xenologue uses the same map as Chapter 23 of Conquest.
  • Even though Shigure is a Falcon Knight in the following Xenologue, this appearance does not affect the cutscene at the end of this Xenologue. Instead, he will use whatever attire the player's Shigure had prior to starting this Xenologue.
